BobHaving collected the Domino Disc subset (HOFers only and there are a bunch!) I can tell you that Lajoie appears more infrequently than any of the HOFers. It is also very tough to get these discs in "rustless" condition, as they are very prone to rust and wear. Lajoie was the last one I found.
Good luck on finding one, I'm sure there are some more out there floating around and with the price that Nap brought, surely someone will free one up for sale.
