The 1975 Jefferson Nickel is very common in circulated condition, as well over 181 million examples were struck. Finding them in circulation should not be difficult as they don't carry a premium in most grades. Only in MS67 and higher are they scarce. With the Full Steps designation examples in MS66 Full Steps are hard to find. Anything grading higher than MS66 with the Full Steps designation is considered a rare coin for this issue.
