I like collecting proof coins because they’re usually exquisite, collector-quality examples of the coins that I find in my pocket change.
But what about proof coins that are less than perfect?
These are called impaired proof coins. According to the Professional Coin Grading Service, an impaired proof is “a proof coin that grades less than PR-60; a circulated proof.”
Unfortunately, not every proof coin is kept in the best condition. Many are mishandled. Sometimes they’re even spent just like they were regular pocket change.
See why impaired proofs may be worth collecting…
