That sounds like it except there's usually a lot of brown in it. It's almost attractive at first but it soon obscures the coin and becomes quite...
Good question. I never even thought of it. I doubt PVC can become air-borne in sufficient quantity to affect other coins normally because they...
No. I've never analyzed it beyond the flame test. But this interior layer sometimes delaminates and it is extremely this and very soft. I...
The mint has been much less than forthcoming about mint sets since 1965. Indeed, one could say they have been quite secretive about their...
There's nothing you can do to a planchet of a given size to make it thinner. Two things though; The edge of a type 2 planchet is upset by...
I'd guess only 35% of them survive. A lot of the coins from destroyed sets still survive but the silver does get melted down. Most of the...
I like this one. These aren't often seen in nice condition.
I can't say you're wrong but I can say with certainty that this attitude or belief is exactly what causes the mint sets to be destroyed. Many...
This is the best way to go. Quality is far better in mint sets and cost is cheap. If you look at a few sets and pick out the nicest then...
I've said this many times but I believe the only reason most moderns are cheap is that there is no demand. No, I don't mean a VG 1966 quarter...
I gotta go with plating. Nickel is non-magnetic unless it's nearly pure. There's no reason a war nickel should be attracted to a magnet.
I think you're referring to the billon coinage. But even this in high grade lists for high prices.
There doesn't seem to be much Tibetian silver in the US (or many Tibetian coins of any sort). Since so much of the supply of world coins exists...
At the current time most of these sets are actually worth more cut up. There are probably ways to delay onset while leaving them intact. I...
Apparently it's both but it's the PVC that is actually causes most of the trouble. The carbon spots on the cents might be less affected by this...
Someday there will be a premium for these sets and if you do what needs to be done you won't get this premium. Personally I believe there will be...
Pre-'85 US mint sets have a thin layer of PVC plastic inside against the coins. This is especially hard on cents and especially on 1968-P cents,...
It's the hard plastic case and very similar to the older Soviet mint sets.
I didn't notice that they switched to a new smaller size in '96 (and apparently discontinued issuance of the 1f). Krause doesn't list a weight...
Like everything reported in the press the story is confused and ambiguous. But the author strongly implies the shortage is not limited to 1f...
Separate names with a comma.
