I should have given the full details - in TGT it is listed as Big Jake's Card Room (Goldberg's) at 670 Main Street.

The Cip Guide has Goldberg Gaming at this address, although your chip isn't listed.

Afraid I don't collect SD so no idea what the connection is, but I'm sure some others may be able to add more. I would be surprised if the entry was a complete error, but no idea what the link with Goldberg Gaming is.

Hope you manage to complete the mystery
