Visible crew/equipment: After Will tells Elizabeth he loves her, she sees Mr Cotton's bird, then says, "I can't breathe." In the next shot, when the camera faces Jack on the gallows, the soldier on the right of the screen steps away from the wall. Very small in the corner, at the far end of the courtyard, you can see a crew member wearing a light blue shirt and cap. (02:06:10)
Visible crew/equipment: When Will and the hangman go at it, there is a close-up of Jack. In that shot, when Jack turns to his left it's very apparent that under his shirt at his shoulders and back, there's an apparatus holding the actor up, in order to help him swing back and forth, and so the false noose wouldn't harm him in any way. (02:06:40)
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: 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: 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: 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: 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.)
Visible crew/equipment: At her home, in the shot facing Elizabeth just as she tries to whack Ragetti with the bed warmer he grabs hold of it and camera equipment is visible at the lower left corner of the screen. Two shots later facing Elizabeth in the same angle, as she and Ragetti hold the bed warmer the equipment is still there. (This is ONLY visible on the video version.)
Visible crew/equipment: At the Swann home, after the shot of Will nodding to the passing butler, when Governor Swann walks down the stairs as he says "Ah, Mr. Turner," a mat is visible on the foyer floor between the chair and table. The mat is also visible when Will flips the sword. However, when Governor Swann, Elizabeth and Will leave the house, the mat is gone. (This is ONLY visible on the video version.).
Visible crew/equipment: When Barbossa's crew are invading Port Royal, two pirates run past Will carrying loot. One whacks Will on the head with a silver candlestick. As Will falls backwards, the crash mat is clearly visible on the ground behind him. (This is ONLY visible on the video version.)
Visible crew/equipment: During the attack on Port Royal, after Will tosses the axe, in the shot facing Jacoby's back as the axe hits him, the blue crash mat is visible in front of him, at the bottom left corner of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: After the pirate pries the gold bowl off his head Elizabeth whacks him, then she and Will stave off the other two pirates' swords as together they hold the gold bar overhead. At the start of the next shot as Barbossa and Jack duel, part of the wood plank that Geoffrey Rush and Johnny Depp stand on is visible at the bottom right of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: After stealing Interceptor, on deck Will sharpens his sword as he says, "When I was a lad...my mother raised me...I came out here looking for my father," and Jack responds, "Is that so?" In the next close-up of Will part of the camera equipment is visible at the bottom of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: As young Elizabeth holds the medallion in her hand in the close-up, the Pearl comes into focus in the distance. In this shot, behind her hand and chain, but in front of the rail and rigging, the top of the white reflector screen is visible as it comes up at the bottom of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: After Will rescues Jack from the gallows they end up on the parapet surrounded by soldiers. As Will and Jack spin around facing the soldiers closing in on them, part of the camera equipment, which moves, is visible at the bottom right of the screen. (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.
