How rare are M101-6s
The recent pick up thread shows an M101-6 Heilmann that I've never seen before. I know Kevin Savage auctioned off a group of these a few years ago that included some previously uncatalogued cards like Sam Crawford. With new cards still turning up, and few ever offered for sale, I'm wondering how rare these things really are. For most of the cards are there only a few known?
