The 1968-S Nickel is a very common coin in all grades, including Gem Mint State, and it is one of the very few dates in the modern series represented by an example in PCGS MS69. Full Step examples are very rare, but not as super-rare as other contemporary dates. The finest example certified by PCGS is the lone MS69 just mentioned (this coin is a full two points better than the next-best examples of this date).
