Judging from your picture I would grade them at quality VF (very fine).
These coins are not particularly rare, so don't expect to have a spectacular trophy at hand. But very tangible remains of one of history's darkest pages they sure are.
Unless they are key dates, they are common junk bin finds in the US selling for 25 cents, but you often see them in antique stores and flea markets on sell for $5 or $6. I have no idea if they sell at that price.
