Never seen what you'd call a "sale" on coins, but occasionally they have non-coin items on clearance, like the old canvas bags, books, and such.
okay.. thanks... yeah thats what I meant Troodon.. I thought they might have some coins go on sale that were left over... but I guess they must melt them down or something....
I have seen them bring back "sold out" products years later and kill the market price of the item. I guess that is sort of a sale.
