For years I bought Mint and Proof sets directly from the mint. What a waste of time, space and money! I finally got smart several years ago and stopped. As a young kid, I thought it would be a good investment.......wrong! Mostly clad crap! I had boxes of them! For the vast (90%) majority, I can't even recoup what I paid for them. So I dumped them, giving them away as gifts to friends, kids, relatives, etc... I've even broken some out and throw them into the wild...... After searching for any significant errors or varieties first, of course.
