Hell just collect old dimes. Any dime older than 64 is worth almost $3 melted down.
Glad I started hording copper and silver coins some 20 years ago, wish I had checked even more as I went along than I did. Not sure how many pounds of copper pennies I have but I can barely pick it up.
Isn't melting money for scrap metal (w/o the proper license) a crime? Hoarding might be legally ok but the use is limited to resale. trying to recycle and purify the silver out of the pre 64 coins is often quote as a criminal act.
I simply bought some us junk coins few years ago. Not so easy to find silver dollars in circulation in EU ; )
the silver quality should be imprinted
I think i would buy one for an reasonable price (maybe 10 - 15 % over spot) and if you consider also sending it to god old Europe

just make sure you stay under the customs/tax limit when ordering, 2-3 max or you end up paying taxes on silver import. this would be immediately 20% to the value of the shipped rounds.
