Good Day! I hope this adds a little excitement to the forum for my first visit. A 4.1 gram light weight, apparently made of aluminum, quarter arrived via a normal bank roll of quarters and the funny thing was that it was not even counted-there were 51 quarters in the roll! This speciment shows a lot of travel and wear from normal use. There is an inclusion in front of Washington's throat that travels throught as a pin hole with sharp enlarged crater edges on both sides-it was not added. I have included pictures here for your pleasure. Since I am in Florida, who would you recommend for the honor of certification? Or, does anyone have any ideas on what else this could be?

Acid would have burned off the features but not reduced the weight to 4.1 grams. We're missing about 2 grams.
A photo of the edge would be informative. With just the view of the obverse and the reverse, it does look like a acid treated coin. Many think that an acid would reduce the high points to low points, but the acid works on all surfaces equally if they are the same composition. So the high and low areas would be reduced near equal. Looking at the obverse, the closeness of the date and motto indicates that the acid has removed about a thickness equal to half of the thickness of the coin ( by eye measurement), so the weight loss would be close. Acid reduces the diameter of the coin and the thickness of the coin and the weight of the coin. It usually reacts more with the inner copper layer than the nickle containing clad layer, and then the coin can be gently pressed, and you have a coin that looks entirely a single metal. Jim
Thanks Jim! Pics attached...quarter measures 3mm on the rim, same as a normal quarters. And this still has a deep grove rim but one sided! Looks like a cracked plated on the reverse since the E is split and the S is almost gone. And the general depth of the letters vary with position. I would think that acid would evenly corrode the surface...this surface does show a strange porousness..degeneration.
