This is more a matter of taste and readability than of grammar; however, the standard tends towards the 1920's.
Apostrophes are not only for indicating possessives; they are also used for plurals of letters (m's), figures (2's) and sometimes words.

For groups of years, the apostrophe at the end cannot be regarded as necessary, since there is no possibility of misreading. For this reason, most authorities prefer 1960s to 1960’s[5] (although the latter is a common Americanism[6]), and 90s or ’90s to 90’s or '90's. --Wikipedia

1920s is right.
Just use the s when showing plurality.
You use the apostrophe when you are showing possession.

1920s is correct.
An apostrophe would show possession,which is not needed here.
