Inorite!
After my first just-for-the-fun-of-it marble acquisition, I was one of those people who started collecting with the hope of making a profit. Learning as I went. I thought it was a CAC, which meant maybe it could help pay for my investments, and I think I got around $50 for it. Now it doesn't look like a CAC to me but I don't have another guess.
Speaking of those early days, man, oh man, do I wish I still had the World's Fair cigar box back with all the beautiful Akros and simple but sweet Master Cloudies which were in it. ... which I got for $20.
