Just found these rolls in a bank. Who deposited them? A collector or dealer is unlikely because they should've kept at least one coin from each roll. The most reasonable explanation is that someone turned in a gift.
That set is still available from the US Mint for $32.95 + at least $4.95 shipping. You got a killer deal for only $20! Congrats. I would keep them rolled the way they are unless you need the cash. HH all.
