The coins look well designed. They are fun to collect, but in collecting coins and currency for numismatic value you focus on quality and not quantity. So condition, material, and numbers minted are the big factors in determining value. I've seen sets on sale on Ebay now of the coins, old and new series, they are tempting, but won't have the kind of investment value as in hoarding large numbers of banknotes with the hope of increased valuation.
On a numismatic level, I don't believe the coins will have much investment value. Too many coins are minted in modern series, so unless there are errors, not much collectors value. Face value is what's important to us. I collected foriegn coins and currency for the fun factor. If you are interested in numismatic values, collect old U.S. coins. There would be foreign coins of value around, but from the 1800's. Had a german .05 equivalent worth $50 bucks.
Lost all my collection in a house fire, including some shekels. Fire boxes are useless. LOL
