I think they were made for a German retailer, if I remember correctly. I have only seen them available from Germany in the past.
The colours are a mixture of the Classic and the National Poker home series on the Paulson Chips mold (not TH&C)
I also think they are faux shaped inlays rather than actual scallop inlays (although I could be wrong here) as I think that the TH&C or 'World' chips were the only shaped inlay chips Paulson produced for the home market.
