Sorry to hear that NumisEd. I've had the same issue at small, monthly shows: these have maybe 90%
US coins and banknotes and bullion. But the 2 big shows I go to (Boston and NH) have a better split, maybe 70:30 US to World coins (ancients too). Each show has 100+ dealers so I'm looking at a good supply of world coins. Anything from bargain bins to 5-figure slabs (out of my price range!). I love going thru the folders and trays and easily spend 6 or 7 hours at any show, I'm always the last to leave. I hope you find a better show with a better selection. They're out there, just gotta keep looking.
