1990's or 1990s

Which one is correct for referring to a particular decade of a century? Is an apostrophe necessary there?

No, it isn't. (I don't use one.)

 

[probus]

The apostrophe is not just unnecessary, it is wrong. The fact that many people use erroneous apostrophes does not make them correct.

I'd write

I bought a lot of records in the 1960s.

I still have a lot of those 1960s' records.
