From the U.S.Mint Superintendent in the 50's&60's

I was just looking at some of my old Proof Sets from 1956 and up and found this what I guess is the COA of the times note enclosed:

Your U.S.Proof Coins--
have been carefully inspected before release!
If there should appear--what may seem to you--a defect or a
scratch on a coin--it is no doubt a crease in the polyethylene-coated
cellophane in which they are encased.
We tell you this to save us both unnecessary correspondence.
THANK YOU!
(over)
Sooner or later your Proof Coins may show evidence of oxida-
tion (tarnish or discoloration).
We have chosen materials and methods of packing that we hope
will delay this possibility, but we cannot assume responsibility for
oxidation.
Please do not ask us to make exchanges or adjustments.
Thank You!

(Mrs.) Rae V. Biester,
Superintendent

I thought with all the different grades floating around today on the new Mint issues that this note fit right in.
The coins I have still look so very beautiful that I'm thinking of sending them in for grading and slabing.

What do you experts on this board think?????
Thought some who have never seen this kind of old note from the Mint might injoy it.

Thanks for posting that interesting note. I recalled the part about the scratch but had forgotten the reverse side about the oxidation. I wonder if the mint actually did do much (or any) testing of the plastic it used to hold the coins? Clearly the plastic was better than the older methods, but I still wonder how much thought was involved.

That note was posted several (about four) years ago... but it is good to see it again. Shows the difference in attitude/service. Very interesting. Cheers, RickO

Take a look in David Lange's Guide Book of Modern United States Proof Coin Sets, which covers 1936 forward. He pictures and describes several different kinds of these notes from over the years.
