Hi Jerry,
These chips are from Slovenia. The names “Park” and “Perla” are the names of the casino. The name of the company is HIT. I think that Harrha’s was looking at buying them are 2004 or so, but backed out. Each location has a different color 1 Euro Chips. The colors are: Red, Orange, Yellow, Green, and Blue. I am not sure which are current or OBS.
My father brought me back about 20 of each about 5 years ago or so. I had been trading them at the trade secession during the conventions.
Hope this helps!
Frank : )
