Proof Coin Questions

As far as I've seen, it really doesn't decrease the value - no. A lot of proof sets, even the older ones, can be obtained pretty cheap - a lot around $10. Now take a look at the price of a Capital holder. Assuming the sell price is the same for OGP versus Capital holder, I think you're getting a better deal with the holder!

Interesting stuff! How long will it take the proof sets in the mint cardboard to start toning? On a related note, what about the uncirculated sets in the paper envelopes? I'm thinking of all the mint sets - uncirculated and proofs - someone bought years and years ago that are in in an old cardboard box.

 

I found a proof Statehood quarter in circulation recently. I figured someone broke into Grandpa's collection and spent the coins for face value.

 

I didn't know that. I should remove them from the boxes?

'Unopened Proof Sets'

When I look online, I see a lot of listings for older proof sets that have supposedly never been opened. I speak of the ones that come in the brown-colored Treasury envelopes. My question is how easy is it to boil a pot of water, use the steam to soften the glue, open the envelope, remove the coins for viewing (or for that matter replace them with coins from a more common date) and reseal the envelope without any signs of tampering? (I saw this technique demonstrated many years ago on an episode of MacGyver). I wonder if the envelope warps and one can obviously tell whether the envelope was opened and resealed? Has anyone tried doing that? Did many people from years long past really buy proof sets and set them aside to never be opened? It is hard for me to imagine something more ridiculous. Anyway, I am skeptical of ads for envelope proof sets that have never been opened. What do you all think?

 

I should have been more specific. I wasn't concerned as much about toning as I was about the effect of airborne moisture. In that regard, the Mint cases do a very poor job if proper climate controls aren't maintained.

All I know is that everything MacGyver did was completely within the realm of reality. Unless you could open the envelope, like you said without warping the paper, I don't beleive it's plausible. Also if you replaced a proof set from a particular year and then got coins from a different year I think you would have recourse with ebay or whomever.
