Proof Or Mint Set?

I do not know a lot about the pre-1968 proofs since I do not collect them, but this should be a proof set. They did not start using the solid plastic holders for proof sets until 1968.

Thats exactly what it looks like. The red and blue strip will help me remember also. I also noticed that my mint sets have two sets of coins in the envelope, one red striped and one blue striped. Thanks for all the replies.

I think the paper envelopes on the proof sets have something like 1963 PC and the mint sets have 1963 UC

I collect Proof sets and Mint sets, Gibby3 said it all, also if the set is out of the envelope, you can tell the difference by the coins, mirror like or business strike,and a Mint set gave you more than 1-cent, also the proof sets were packaged differently in the mid-50's the coins were in a small cardboard box and all coins were in single "cells" of cello packages, held together with one staple,usually the older the set, the more delicate the wrapper. I believe this style packaging started in 1947, and ended in 1955, be well, Mike...
