Proof or mint set?

Can anyone tell from these images if this is a proof or mint set? In hand the penny and the nickel certainly look proofy, the silver coins, less so. All the coins have heavy dip polish.

Proof set... why would you think otherwise?

P.C. on envelope means Proof Coins.

And what is "heavy dip polish"? 🤔

Most definitely proof set. I mean dude look at the cent

"All the coins have heavy dip polish."

What does that mean, or imply? Specifically for coins in 1957 Mint sealed cello packs.
Thanks.

Here is a close up of the half dollar with the die polish

Positively a 1957 proof set. The original mint uncirculated sets came in cardboard sleeves and with double numbers of coins. Here is an original 1957 United States Mint uncirculated set.
