I've been doing that for more than a decade. Went to the local rinky-dink annual coin show, and was disgusted by the bullion premia. Started looking at foreign coins.
Went to one table with some foreign coins and asked if he had any Canadian--he laughed in my face. Found another table that sold me Canadian dollars sealed in plastic for below melt. Guess he was tired of them.
So I picked up some Dutch, some Canadian, a Chinese dollar before they went crazy in price, and a 1950s Swiss 5 franc that was marked as .75 ASW. Didn't know anything about foreign, so I went on line to see what I had. Found out I had been cheated on the 5 franc.
Started buying used Krauses online. Was in line at the LCS, and forced to kill time, I looked at the foreign junkbox. There was a 1950s Swiss 5 franc. I asked how much the coin dealer wanted for this junk box coin. Answer: 25 cents. I was fairly sure the coin had not been demonetized, and a Swiss franc was then 80 cents US, so I figured I had a $4 coin even if it wasn't silver. But, of course, it was.
FWIW, at a later (and different) coin show, I brought 280 (nonsilver) swiss franc coins to a foreign coin dealer. This was when the Swiss franc broke the Euro peg, and was marked at something like $1.20 US. He gave me 90 cents for each franc, and I bought a gold French 20 franc with the proceeds. These were coins I had paid 5-6/$1 to obtain, ranging from half francs to 5 francs, so I didn't have much money in them.
Now, a major part of my collection is foreign silver obtained either in the 5-6/$1 junkbox, or at a spottish price. If the LCS holds coins for me to review, I pick out the silver for them (often setting aside the silver I want to buy). If they throw it in the junkbox, I figure it's free game. And yes, I have found gold in the foreign coins I reviewed.
Was in the LCS recently, and a customer said -- hey, the world coin guy is here. So I guess I have a reputation now.
