I'm new to coin collecting and the reason I found this community was because I searched the web for "1946 2.5" because I have one that weighs exactly 2.500 grams. It doesn't have a pattern on it like the OP's coin.
Going from 3.11 grams down to 2.5 means that the coin would have to lose nearly 20% of it's original weight, all coming from the surface of the coin.
My coin is probably a ground find because it does have some erosion, but it struck me as unlikely that I can still make out some details with almost 20% of the coin gone.
I thought it could be a planchet error because it is visibly thinner than it should be, but it's still the same width of a 1946 in great condition.
Maybe it is just damage, but like the OP, I really wanted it to be special. :D
