Double check your scale on another sac dollar and some other things and be sure it's accurate.
The possibility exists that this is a Sac dollar struck on a 1999
SBA dollar planchet, there's an overlap there for the two coins being minted at Philadelphia, the
SBA through 1999 and then on to the 2000P Sac at the end of 2009.
Coin should not weigh 7.6g though. it should weigh 8.1 either way. A more than half gram is huge over or under, and while they do have a .5 gram tolerance limit, that one would be right on the edge of unacceptably underweight.
I don't think it could be plating.
No other denomination short of a completely foreign planchet for a different country gets you to 7.6g (possibly), which is why I suggest the scale might be off. A 3-4 decimal place scale won't be off by much and be pretty precise, some of them will round though if it's a 2 or 1 decimal place scale, or just be off by half a gram (also a tolerance thing and acceptable for the manufacturers of some of them.)
Examples struck on a
SBA planchets have been found and exist. If it's 7.6g though I'd have to think it's a fake of some sort. No idea how it could be a half gram underweight and look that good still, it's lacking some detail on the reverse, the tail feathers, the wing tips, the eagle head and body the feet, I think her shirt on the obverse should have more detail also, which now looking at it more, it's less noticeable at first look but it's lacking detail like hair strands on her and the baby, also, I think just an overall lightness on both sides, and not sure why that would happen, underweight maybe?
PMD and someone spent a lot of time wet sanding it down and that's where the half gram went? Hard to really say.
You could also measure it with calipers, should be 2.00 mm (0.079 in) thickness, 26.49 mm (1.043 in) diameter. Same goes for the
SBA coins, they were different metals, but same sizes and weights.
Also if you can please take a picture of the coins edge, I'd like to see that too please.
By the way, in 1998-1999 there were also "experimental planchets" testing for the Sac dollars with
State Quarter and for
SBA dollar dies, with some examples found since 1999. of
SBA and
State Quarters struck on them, they have a "greenish" color in most cases though or were the same color as the SAC dollar coins, but those weighed in about 7.3-7.6 for the
SBA coins they struck with them. I don't think that's what you have though... color is wrong, but that could be lighting also of the picture of course....
