Of the US coins I see nothing of big value. The wheat penny maybe a few cents The half dime, maybe a few bucks The indian cent looks to be in a nice condition, but I see no luster, so maybe an AU50-53, might be worth around $10-$12 As for the foreign coins, I HAVE NO CLUE
The true issue date of the Spanish peseta with the frozen 1975 date (KM#806, al-bronze) is actually 1976-80. The real date is incuse in the tiny six-pointed stars at the bottom of the obverse.
