Unites States Mint proof sets are a fun an profitable way to combine coin collecting with investing. Proof coin sets have historically been a great long-term investment as well as a fun hobby for younger collectors. The value of these sets goes up over time and they have a wide range of collectors outside the numistmatist community. Collecting mint sets, proof sets, silver sets and other US Mint offerings allows the novice collector the opportunity to build a portfolio of coins while learning the ins and outs of the market.
