Ron--how did you arrive at the 27 figure ? Would that mean you think there were 9 sets produced ? SCD lists them as existing in gold, silver and bronze colors, do you think there are 3 of each. SCD also says some have holes in them, maybe for a chain. Any info on whether such holes were part of the production process for some of the coins, or made post production by 3d parties who acquired them ? Have you come across anything indicating who Topps used to produce them ?
I think I mentioned to you that several years ago that I bought a gold colored Jackson on ebay and the seller then offered me a full set of what look to me like tarnished bronze colored ones. After I got those I relinquished the Jackson to another collector who has since picked up either a Carew or Garvey, can not remember which
