Q: What does PR68 mean? Is that a good rating? What's the
best rating?
A: Coins are graded on a scale of 1 to 70 with 70 meaning in
flawless mint condition and 1 being extremely poor. This grade number is
prefaced by a variety of prefixes adding further classification to the
coin.In this case, the “PR”
designation in front of the 68 (which is close to 70 except for some very minor
surface defects in the coin, probably only noticeable with a magnifying glass)
means that the coin is a “proof” strike which is a special strike struck for
collectors with a higher striking pressure and a more polished die, usually
including frosted surface areas for a more beautiful picture on both the
obverse (front) and reverse (back) of the coin.
