does changing '60s mint sets from cellophane to plastic cases hurt value

i have a bunch of early '60s mint sets that i still have in there original cellophane. i was curious if they would lose any type of value if i was to put them into plastic mint sets holders??? i think they would keep the coins more protected that the cellophane. any info would be greatly apprciated

I would keep them in the mint pack, the 2nd one you showed is not a mint pack.........

 

Usually original government packaging commands a premium. Possible exception would be if there are some high MS examples that you want to get graded by PCGS, NGC, or ANACS.

 

it was in the mint pack. i took it out and then put it into the plastic case. after doing one set i started to rethink doing all my 60's sets. i think i will just leave them in the cellophane. thanks for the input

 

Good idea.

 

LEAVE them in the mint package. IMHO you are removing value by opening the Mint packages and putting them in the plastic holder.

 

Be Careful!

I read your post and initially thought you were referring to "mint" sets which would contain both Philly and Denver sets. Also the envelopes for those sets are white not manila. Then a figured you said "mint set" and meant "mint proof" set.

In any case you should be aware of the following things:

1. There are sellers who repackage sets, print new envelopes and pass them off as original.

2. Sets that the cello is so degraded because of poor storage practices have lost their ability to
protect/preserve the set. Plus it makes it almost impossible to view the set with enjoyment.

3. There were millions of these sets produced with the exception of 1960. Breaking out sets
that are in less then perfect condition isn't hurting anything.

Most importantly these are your coins and unless you intend to sell them do with them as you wish.

I personally love to collect silver proof and mint sets 1964 and older. I do not keep my prize collection in their original packaging because I don't intend to ever sell them and I love to view them often. However I do like having a collection of original packaged sets "that are original not reproduced" just for the sake of having them.

Do as your heart desires and Keep on Collecting!!!

Leave them in the pkg. how do I know that the plastic set you have is not just a few UNC coins put together. In this case people are buying the wrapper as well as the coins

 

if they are mint sets leave them in the original packaging and if they are proof sets then do what you want because the value is basically the same for proofs in each.

Either way the sets are extremely cheap (worth only slightly more than the bullion they contain) so it really doesn't matter much what you do with them, they will not be particularly valuable in our lifetime regardless of how you store them.

Thank you Allen... I agree wholeheartedly. Do what you want with what you have purchased or obtained. Enjoy them. After seeing hundreds of these cellophaned or plasticized prisons for coins, I realize that neither container can keep them safe and true to their original form. What was thought to be safe for storage back then is no longer accepted as proper storage by archivists now.

So, urban chemist, if you want to break these out of the container and put them in flips go right ahead and do it. It all comes down to the decision that is right for you.

I would also add that the original mint cello packaging protects the coins better than the Capitol plastics holders, which are not air tight and can permit toning to occur.

 

Mint wrappers

After receiving my first few 60's mint sets in those yellow envelopes with the two pieces of cardboard meant to protect them I realized that upon opening the supposedly unopened sealed envelope (they were not suppose to be sealed shut in the first place) the contents smelled extremely musty. Like an old book in a library.
A musty environment is not a place where I would want to store anything, much less lovely coins.
After all, did they have acid free cellophane, cardboard or envelopes in use at the mint in 1960? I doubt it.
Apparently it was in the 1950's when acid-free paper was made possible by technology. Unfortunately it took decades until ANSI NISO Standard Z39.48-1984 when the standards were adopted.

Just a point of view about those protective envelopes...

thanks for eveybodies feedback. i think i am going to take the out of the cellophane as some of the campartments have become open and the coins have shifted on some of them. plus so of the adhesive from the cellophane wrappers are coming off on the coins.

 

I have an American Buffalo coin and currency set in the box the mint sent it in will that harm the set?

 

Not even the cellophane ones?
I have several 1982 Washington half dollars in the original mint cello that are absolutely pristine after 26 years. Same for all the "flat pack" proofs sets I have, some of which are much older.

I agree that the plastic lenses that proof sets came in since 1968 are not airtight. Some of the coins in those are discolored.

 

just dump it as in an intercept shield box if you are worried about toning assuch

 

case

just keep the original. anything initial offered by the u.s. mint.
