I can neither confirm nor deny that such chips exist. But if such things did exist, and if I somehow were part of the original purchase, then the question would be " did I buy spares in case my full racks lost a few chips "
While I might confidently point to a 1000-chip bird cage in the left corner of the top shelf of the vault - it might not have a single one of these mythical chips. And looking for perhaps non-extant spare chips isn't that easy - those aren't something I could point to one box and say, "of the hundreds of boxes in the vault, that box would be the proper place to store back up irreplaceable chips from a decade ago"
Yes, it is true that I might have participated. But it was soooo long ago that my feeble memory can't be reliable. -=- DrStrange
