Visible crew/equipment: Just as Jack says, "On deck, you scabrous dogs," to the very left edge of the screen over Jack's shoulder is a grip crew member with a tan cowboy hat, white short sleeve tee shirt and sunglasses, just standing there looking out to sea. (02:12:35)
Visible crew/equipment: When the Interceptor is totally blasted by the explosion of the gun powder deck and after Pintel says, "Any of you so much as thinks the word 'parley', I'll have your guts for garters," just when Elizabeth goes under the rope, one can see a man with headphones on his head and a megaphone in his hand in the lower left corner of the screen - it looks like Gore Verbinski, the director (this is only visible on the video fullscreen version).
Visible crew/equipment: At the blacksmith shop, Jack and Will start to duel and Jack asks, "But how's your footwork?" In the next close-up shot of their feet, the imprint of a modern, flat bottom trainer/sneaker sole can be seen on the dirt floor at the bottom right of the screen. It is not the imprint of a heel and sole of the time period. As a point of interest, on the video version of this film there are multiple imprints visible. (00:23:25)
Visible crew/equipment: When the dock master tells Jack, "Hold up there you. It's a shilling...," seen in the background on the left of the screen is a thatched roof enclosure. An orange aluminum ladder is sitting under the thatch. Many of the crew's orange aluminum ladders of various heights can be seen on DVD 2. (00:10:10)
Visible crew/equipment: When Jack and Barbossa duel in the cave, Barbossa hits Jack in the face. Barbossa yells, "Aaaah," and Jack takes off running with his arms waving wildly in the air. In this shot, as Jack waves his arms, at the bottom right corner of the screen, the wood scaffolding that was built for the cave set can be seen near the rocks in the water. The cave set scaffolding can be seen being built on Disc 2 of the DVD. (01:57:20)
Visible crew/equipment: Jack is in one of the boats with Norrington and his men, at Isla de Muerta. Norrington looks through the telescope, saying that he doesn't care for the situation and in the wide shot, when Jack says, "Not if you're the one doing the ambushing," in the water, to the right of the boat, a crew member's green flipper can be seen coming up out of the water. The divers kept the boats steady while filming. (01:43:05)
Visible crew/equipment: After Will tells Jack that he can get him out of prison, he lifts a wooden bench to use for leverage and says, "And the proper application of strength..." In the next close-up of the bench as it's positioned at the cell bars, a crewmember's fingers are gripping one of the bars at the bottom right corner of the screen. (This is only visible on VHS.)
Visible crew/equipment: Just after Will cuts the lines from the Interceptor to the Dauntless, the Interceptor is shown leaving. The next shot is of the back wood plank between the ships falling away. On the deck of the Interceptor, behind the railing, on the right of the screen, is a crew member ducking down, so as not to be seen by the camera. (00:47:10)
Visible crew/equipment: Before being marooned on the 'spit of land,' Elizabeth stands on the Pearl's gangplank. In her close-ups, with the island in the distance, the long 'metal pipe' guardrails are visible behind her in three shots where she is still wearing the dress. The pipes are also visible behind Johnny Depp (Jack) in three shots, including when Barbossa says, "That be the same little island we made you governor of..." In all other shots of the gangplank there are NO guardrails surrounding the actual gangplank while it's extended over the water. (This is only visible on VHS, but can also be seen on DVD 2 and DVD 3 - 'The Lost Disc'.)
Visible crew/equipment: As Norrington says in the wide shot, "Jack Sparrow, isn't it?" to which Jack replies, "Captain Jack Sparrow, if you please sir," there is a black-haired crew member wearing a white shirt who is crouched down behind Jack. Really! He's also visible when Mullroy says, "These are his sir." (Visible ONLY on the video version.)
Visible crew/equipment: As Will and Jack duel up top in Brown's shop, in two close-up shots a large plank is visible at their feet with two long black marks along each side detailing where the beams are supposed to be, so that Orlando Bloom and Johnny Depp know where to land as they supposedly leap from beam to beam and feign keeping their balance. (This is ONLY visible on the video version.)
Visible crew/equipment: On the dock, when Jack grabs the rope, flies up and escapes, the cannon comes crashing down onto the dock. When the wood planks break (pre-cut wood), two Marines fall into the hole. Seen hanging under two of the remaining fixed wood planks are strips of tape that was used to help secure the pre-cut wood together with the fixed wood. Another view of this is also seen on DVD 2. (00:19:45)
Visible crew/equipment: Will grabs the red hot sword and during the 'white light', Will's sleeve becomes translucent so the cable attached to the hilt is seen inside Will's right sleeve. When Will thrusts his sword at Jack's legs, the cable's seen again and the bulge under the vest is from the battery pack. In the close-up, their arms in the air, Will's left hand is about to grab Jack's wrist and the cable is seen openly at Will's wrist, going from the hilt into his right sleeve. The cable's hidden in Orlando Bloom's shirt and is powered by the battery pack (mentioned in another mistake), to supply the power for the spark effect of the sword. (On disc 2, Marc and Tony, rehearse this particular sword sequence and the two cables leading from the hilt are seen dragging on the floor as they duel. On the video, the cables are visible on Johnny and Orlando.) (00:24:15)
Visible crew/equipment: When Jack and Will duel, Jack says, "You need to find yourself a girl, mate," and he takes a mallet from above, Will ducks. In the next back shot of Will as he ducks, the back, left flap of his vest goes up. There is a battery power pack secured with black tape to the left side at the back of Orlando Bloom's pants' waistband. There are several shots during this scene when a small bulge under the back of his vest can be seen. (00:24:45)
Visible crew/equipment: During the cannon attack on the harbour near the beginning of the film, a spring board, used to propel one of the stuntmen dressed as a sailor into the air, is visible during an explosion near the dock. (00:30:20)
Visible crew/equipment: At the blacksmith shop, after Will grabs the sword out of the fireplace just as he and Jack begin to duel around the post, in the wide shot, black straps with attached wire cables are clearly visible around both Johnny Depp and Orlando Bloom's right ankles. (This is only visible on the video version).
Visible crew/equipment: During Jack's escape, he swings about on the rope. As he does, in the shot immediately following Jack's first close-up, the film crew's blue flat-topped boat, as well as their speed boat with its trailing wake, are both visible at the bottom left of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: As Norrington and his men board the Dauntless he says, "Search every cabin, every hull down to the bilges." In the next shot a crew member with a white baseball cap and green shirt is actually visible hiding under the gangplank. (This enjoyable shot is ONLY visible on the video version.)
Visible crew/equipment: After Will admits to Elizabeth that he loves her, she looks over and sees Cotton's parrot sitting on the flag post. Mullroy is also watching as a black-haired crew member, wearing a short-sleeve, white tee-shirt, can be seen holding the post and shaking it with his bare arm to get the parrot to fly off. (02:06:00)
Visible crew/equipment: On Isla de Muerta, Barbossa yanks the chain off Elizabeth's neck, grabs her hand and in the next shot as he places the gold medallion in the palm of her hand, the crew's metallic reflector screen is clearly visible on top of the Aztec gold chest, it even moves a bit. (This is ONLY visible on the video version.)
Answer: The curse needs the blood of everybody who took a coin from the chest. All the other pirates have already contributed so, as the movie opens, the only blood needed is Will's, substituting for his father. During the finale of the movie, Jack takes a coin from the chest, adding himself to the curse, so his blood is now required as well as Will's.

But I didn't see any blood on the coins, and none of the pirates cut themselves, even before Will became part of the mix.
Yes, the other pirates did cut themselves before Will came into it, off-screen. The lack of blood on the coins can simply be explained as most of it dripping to the bottom of the chest, it being washed away by storms blown into the cave, or by the fact that they didn't drop that much blood on it in the first place.
When they had Elizabeth they believed she was Bill Turner's daughter, but they all thought the curse had failed, none of them had cut themselves so it makes zero sense.
They had been collecting back the coins for years. During that time they repaid their own blood. All they needed was the last coin and the blood of Bill Turner to break the spell.
