1970 S Lincoln Cent

According to the RedBook, the mintages were

P- 1,898,315,000
D- 2,891,438,900
S- 2,632,810

There are also small date and large date examples for 1970 S, small date being worth A LOT more than large date. Sorry, I don't know how to tell the difference, although I've seen at least one thread here that covered it.

There is also a doubled die obverse in the RedBook for a 1970 S.

If you could post a picture of it, I'm sure someone could tell you if it's a samall/large date. If large date, the RedBook values it (in unc. condition) at 35 cents, but for small date, $65

There are two different 1970S Lincolns- the proof(mintage 2.6 million) and the business strike with a mintage of 690.5 million so it is definitely not scarce but it is also not common in current circulation(none of the 1968S-1974S business strike Lincolns could be considered common in circulation any more). Both the proof and business strike have a small date variety and both have a significant premium and those are certainly considered to be quite scarce.
