Might want to post the foreign stuff in the relevant forum. Looks like you have some 90% silver, so those will always have some value, even if it's not numismatic value. You also should maybe post individual pics of the coins in the "whats it worth" subforum.
you would need to list the dates of the pennys etc there may be value for certain wheats. check the forign for silver. and if the dimes are pre 64 then thee silver
I see some silver for sure, so yes, there's some. If you're patient, you can pretty much get $0.99 for anything on eBay. Take out the stamp, envelope, PayPal fee and eBay fee, and you're going to net about $0.15, and hopefully get some nice feedback.
Some collect it as bullion. Look up the 1 sol from Peru, nice silver coin as well. The silver content is not the same through the years for both coins. Suninjune
