A lot more than you know. I pass on a lot of them. These were just too cool to not keep. The Zincolns I have been looking at are so dirty (even after I clean them off) it makes it hard to catch anything good. I mostly keep Die Cracks and Die Clashes. Plus, we are looking at mostly the leftovers that nobody wants. The good stuff can usually be spotted with the naked eye and are long gone out of circulation. But some people do get blessed with a good find every once in a while. It's still fun and interesting looking at the crumbs. Search on!
