Also wanted to add that this selller does not concentrate on sports-related items or memorabilia. Most of what he was selling was misc. antique stuff from various estates. No other sports memorabilia, or anything sports-related. It's not like he was an "Acofind" or one of those other Ohio-based sellers with a track record of counterfeits.
Why would he go to the trouble/expense of making these rather unattractive and aesthetically unpleasing examples? Why pick a style that required the application of the grommets? It makes no sense, and there is no evidence to support this accusation. Especially when there are other identical exemplars from past auctions, offered via major auction houses.
Editing to note that the un-dated Browns example sold for $273. Here are links to the two that were not linked above...
