Its seems that there is a large percentage of modern proof coins (mostly the silvers) that seem to haze up. I have even seen some modern commemoratives listed on ebay from 2011 that are hazed. The silver eagles don't seem to haze as much proportionally as the others (may due to silver purity)? So what is the storage condition that causes the hazing? Too hot? Too cold? Too humid? Stored in the original velvet box from the Mint? |

Well a lot of things can cause that but the only thing I would suggest to you. Don't purchase them, that way you won't be bothered with em.

IMO, a lot the hazing with modern coins is due to poor storage. At one time the Mint's OGP could have contributed to the hazing, but the Mint has moved away from that harmful packaging.

I think ALL mints could do some research on how their coins are to be presented after sale, long term.
The spend lots to make packaging LOOK right, now it the time to make the packaging DO right.

I personally feel like ultra modern proofs are just set up to have issues from how "prrofy" they are. Theyres absolutely nothing that can be hidden on them and the slightest issue that may not have really stood out on an older proof sticks out like a sore thumb now. |

My 1999-2013 cupronickel clad proof quarter sets all look as fresh as the day they left the mint. I remember the silver proofs started hazing within a couple of years, therefore I sold all my sets and only stuck with the clad proofs. As much as I hate to admit it, the cupronickel clad alloy is superior to silver for coining.
Hard to believe it's been 15 years since the design change in 1999.

I have proof sets starting a long time ago and up to now. NONE of them have anything in the way of hazing. Just stored in places with no humidity.

my clad proof sets look fine, my oldest being 1986 and it looks brand new. I think the hazing happens on the silver proof sets

The silver Eisenhowers are a prime example (brown box). I see more milky looking ones than I do clear!

Improper storage. That was my main question. What is the main factor in the improper storage of modern proof coins? Edited by jack jeckel

I have bought a few of the US and Canadian proof sets and NONE of them were sealed.
the cases are snapped together and not sealed so they are quite vulnerable to the atmosphere.

In my experience, the main cause is humidity, accelerated by temperature changes that trigger condensation or evaporation.

Given that they haze the same way whether they're in New Orleans, Denver or Cincinnati, I'm thinking the Mint's planchet prep process is at the root of the problem.
