Very interesting. Thanks for the news. Is there a redemption period for the old coins and currency and is it over yet?
I don't think either are mint set. The '85-D is very nice.
It gets worse yet. There are two types of the each BU coin (P & D mint) for each issue from 2005 and later; regular BU and Satin Finish (SF)...
There are a lot of world mint sets that have or will be going through the roof over the next fifty years. Coins for mint sets are often the best...
You can see one delaminate once in a while. I don't know what's causing the effect but had assumed that it was an extremely thin layer of...
I really prefer a mixture of solvents. But it is imperative that you don't use water or allow the water from 91% to accumulate to much. I...
I would be very leerly of trying to clean proofs. I might try it but would certainly practice on junky ones first.
If you use isopropyl on clad be certain to use 91% as water will cause dark spotting.
I'm still learning how to do this myself. Generally it seems any soak over two days is a waste. It's better to get them out and soak them...
That haze should come off in one or two acetone soaks and rinse in warm water. If the set is still clean there's probably no rush to do...
Remarkable! Most people don't realize how tough these coins are in mint state. They come fairly nice if you can find onme but very few are as...
I just don't know. But I do know that these are four layers of plastic with two on each side of the coin. The two inner layers are very very...
Wear on a coin always starts on the high points. If you tip the coin sideways you can see these high points up above the coin surface. This is...
These are striking characteristics rather than true errors. Apparently the dies were plugged up with a little debris in a few of the letters....
I should mention that the 40% silver halfs are usually the first coin to get hazy. These tend to be more difficult to restore too.
This is most unusual. I've not seen a '68 penny without carbon spots in many years in the mint set packaging. 95% of these are just terrible...
Look at enough mint sets and you'll see these delaminate. I think it's usually caused by exposure to acidic enviroments but am not sure. If you...
These sets are composed of four layers of plastic and the inner two contain plasticizer. This was especially bad on the '68 and '69 sets but...
Russian coinage was extremely lightly saved and the mint sets were widely dispersed and suffered very high attrition. Dealers often cut these...
The inside of the cellophane is lined with PVC and this is not a stable enviroment for coins. If you'll look closer at the '68 cent you'llsee it...
