What should the shul gabbai tzedaka do if he finds someone gave a US Silver Dollar worth more than a dollar? Assuming he knows who gave the coin, should he inform the individual of the greater value of the coin? Also, if the individual says he’s giving the silver dollar, for whatever it’s worth, to the shul, can the gabbai exchange the silver dollar with his own dollar bill and keep the coin?
We can probably assume that the donor knew that the silver dollar is worth more than just a dollar and wanted to give the true value to the shul. So the gabai should have the coin evaluated by an expert and give the true value to the shul and not just a dollar if he wants it for himself.
