Why would you think that? (dylan) those chips aren't the typical Top Hat & Cane. The mold is different enough that most buyers wouldn't know one way or the other. It will not surprise me at all for one of the more experienced members to ID these as vintage chips
These are likely not made by CPC, probably ASM or Burt Co. or some other older company. That same Etsy profile has a nice MD-50 set for sale as well. Old chips.
