Double ingots, found in Illinois together long ago, with matching marbles I've found since.
This sextuplet was in the same group and measures a near perfectly round 1 1/8" (w/o the nub ) - it's Bill's now.
Super collection, Alan, thanks for sharing. The pic is great too. I may have to keep it on my desktop for a while so I can absorb it all - it's really great!
