2012 Baby Proof Set

I would imagine that it would add quite a bit of value. I would probably pay an extra $100 on market value.

I was thinking about this and see that Nancy has already asked the question. At first I assumed the coin had a die rotation but then got to thinking that you probably just meant it was misaligned in the packaging. If it was just misaligned I cant see it bringing any premium, infact some people would probably be less inclined to want it.

That happens all the time with proof sets.
The only coin that WONT rotate is the 50 cent coin.
This is easily resolved , simply remove the coins and put them in 2x2's and add them to your collection.
I do this all the time, it is the ONLY reason I buy a proof set or any coin in mint packaging

Hi Trout1105, I know you always take the coins out of the packaging, and after joining this forum and finally noticing the effects of prolonged PVC exposure on a number of my earlier coin sets ... ... I have starting placing my early unc mint coins into 2x2s.

But, before I do this with my sealed coins sets and all of my other bits that are neatly packaged, I have two queries:

1. Does opening/destroying the mint packaging decrease the potential value/resale price?

2. Once affected by the PVC grunge, how does one remove it from coins? So far, I haven't been able to budge it by either gentle soapy wash, olive oil, or acetone. I am not game to use my favourite solves-everything-in-the-house-and-yard product (WD40) on my coins - but I am tempted as it removes so many other types of grunge.

Thanks, M

PS maybe I need to shift this posting into another forum thread?

Are you using pure acetone purchased from a hardware store? If you're using any other form of acetone (eg. nail polish remover), don't use it any more, but get the pure stuff. All large hardware stores will have it, usually in a 1l tin or plastic container for around $10.00.
