These are boulders from an Alox bag which I got in 2008 from Nancy Frier. I thought I remembered knowing about this style of marble before that time. But maybe not knowing where they came from.
And I thought I remembered seeing Master and Penny King bags containing them, which may have come to my attention around that time but were in circulation before that.
Now the dates on these 1"-ers is being questioned. Also when they became available to the public is under discussion. What are your memories of them?
Correction: Okay ... the question has been updated. It is agreed that the marbles were seen before then. The question is now what packaging they were seen in before 2008, or what packaging they came in which didn't come from a stash from the Alox factory after it closed. Thanks!
