Gold plated silver dollar what is it worth?

Ive been researching this myself. So far I've found out $1.00 if YOU'RE [your] lucky. Gold plating alters coin. I've been told it can not be circulated. You're lucky if you can find someone who wants it.

More, and correctionsFirst, unless you're sure that the coin has been plated, ALL presidential dollars are gold-colored because they're struck in manganese brass.

Second, even if the coin is plated there's nothing to prevent anyone from spending it. It would be almost indistinguishable from an unplated coin because as noted, they're brass.

The rest of the comments are correct. The amount of gold needed to plate a Presidential dollar is so small that it would cost more to remove it than its value as raw metal. It's effectively just a curiOSity, and is still only worth face value - one buck.
