I Bought This Box Of Foreign Coins At An Estate 6 Months Ago. Help?

There are 3 one Piso coins.It's like a very large jigsaw puzzle I can't seem to let go of or put the pieces together

Sorry to keep posting but finding the error U.S made me dig deeper cause there was a1918 5 centavos I thought might be a mule but date is to large and there are multiple 1970-s pennies, thought all small dates but now I'm reading to far into every coin which makes my mind run in every direction and skip something.I might be out of my mind, but I feel the collector who originally put it together knew their foreign coins. There is a receipt in there to a woman who the box did not belong to for $100 with no date or any other information and before I started sorting it just looked like a box of worthless coins

Here is a reply from my buddy that has surplus KM catalogs:
"I have 10 of the 20th century catalogs, ranging from 1976 to 2003, but I've decided it's too much trouble to try to sell them on ebay and may throw them out with the paper recycles. Finding a box and paying the postage just isn't worth it. However, if you can put someone in direct contact with me who wants one (or more) of them, I could probably work something out."

Thank you

Just because there are multiples of the same coin, does not mean that they are all different or that the owner "knew their foreign coins" and had a reason to keep every single one of them. It could simply be a "hoard", rather than a "collection". Not every collector gets rid of their duplicates.

For example: I see a tin with a whole bunch of Netherlands Antilles 5 cent pieces, plus at least a few other Netherlands Antilles coins scattered about the place. This would be a very typical "holiday hoard" from someone who went on a Caribbean cruise and kept all their spare change while visiting the Dutch Caribbean islands. Or perhaps they simply thought the square 5 cent piece was exotic and unusual, so decided to keep them all.

Likewise, if there's a whole pile of British and Indian coins of the same date and type, it's likely just "holiday money" souvenired from a world trip.

Thank you so much, that makes sense

I wouldn't use Krause (or any catalogue) as a price guide. As another poster suggested, ebay sold listings is your pricing friend. And coinoscope app with numista should help ID the coins and key dates etc. I might be interested in some if I knew what was there.
