My rule is Proof Sets after 1990 seem to be stable in OGP, with exception to Silver Proofs from 1992-1998 are developing haze. Anything before 1990 has a risk of hazing in hard plastic OGP. 1964 and before Proof Sets in OGP are prone to hairline scratches and hazing so never handle them! I have all of mine in capsules and have no problem with them either hazing or scratching. They,re also easy to grade if not in the OGP. I send in the cameos for grading and just keep the rest for future sets. As for mint set coins, most are hammered anyway and once in a blue moon, I find one that,s good enough to grade. The rest go into Dansco,s for the grand children. As for the Ikes, etc...their OGP is horrible on the proofs so they,re treated the same as my proof sets would be. Silver Ikes in the OGP are tougher to grade so I treat them the same as I would the mint sets in OGP. Only time will tell for the modern OGP,s after 1990. If I live another 20 years or so, then maybe I,ll know the answer.
There is a market for both, I currently wouldn't spend the money to grade a mint set. Whats really weird is when I sell graded coins on ebay most people want the OGP that came along with the coins
I have all my mint sets in the boxes the mint sells for proof sets. I buy them from a local dealer for a really cheap price. I put a silicone package into each box, change it out when I remember to and I haven't had a problem, in to many years to count, with the OGP.
Does anyone remember the "American Legacy" sets that were introduced in 2005 and lasted only 2-3 years? The 2005 set contained the John Marshall & USMC commems in addition to the clad proof set. The entire set came in a "fancy" display case (read...pasteboard) for a mere $135. Would you like to guess what they sell for now? I bought four of them from the Mint. Boy, was I stupid! Chris

I just put them on a shelf in a bookcase.
Wouldn't be fair, they didn't have a special mint set in the state quarter series (Four of the 'states' aren't states, they're Commonwealths.)
Back to the original topic - let's say the amount released is at 5,000, unlike mass produced mint sets at more than 50,000. Can you still say the same? Personally I have not qualm if coins are broken from common mint sets. However when they become scarce, OGP can make a difference. I remember a while back when I was buying mint sets, this series had wooden boxes. Those were really cheap back. Most sellers back then normally threw the boxes away as they added to postage fees. I was happy to pay extra. Price difference these days is easily been two times with and without the box.
