Can someone tell me what these spots are on my 1oz Silver Maple Leafs please. They are still in the original sealed plastic pouch they came in. What are the spots from? All the coins are in the original pouch, sealed, and in a red coin box, in a gun safe. Doesn't seem to be the green PVC spots I read about on this site. I dont remember these spots being on them when I bought them (its been a year or two). The gold coins I have stored in the same coin box, in soft flips dont have any spots on them. I am going to replace all these pouches/containers right away, see this thread. I came home today to check my coins and I freaked!
Yuk! Never seen that on my Maple's! Have you tried warm water to remove them? I do know Maple's are insanely reactive because of the silver content, and the spot look like some sort of machining, cleaning, or protecting fluid used at the mint?
As I understand it, the spots are caused by insufficient rinsing after the planchets are washed. Many ASE's have the same problem.
So will they harm the coin? Do they detract from the value at all? Is there anyway to remove the spots? These are bullion coins, so I would imagine the "look" is of no concern as the weight of the metal is whats important. However, I would like them to look spotless just because thats the way I am.
ASSUMPTION: My analysis is correct. 1. I don't believe they harm the coin. 2. Yes, they detract from the value since many people them by date, but if there's no date on the Canadian pieces (i.e., they are truly bullion items) then the amount is minor. 3. As for cleaning them, I would suggest an acetone bath followed by a distilled water rinse and finally patted dry (not rubbed) with a clean, lintless cotton cloth. If my assumption is NOT correct then 1 and 3 may be wrong and 2 stays about the same.
I have seen milk spots before but nothing like that. I would sell it and buy another one. Consider storing in Intercept Shield holders. I have my ASEs in them and not a sign of toning, etc. TC
I had no idea that Canadian 1oz coins are not dated. Is there any way to place an approximate date such as the older ones have a vintage look? I mean do the ones in 1988 look the exact same as the 2011?
I have about 2 or 3 Maple Leaf coins with this issue. Could NCS be able to remove milk spots? I'm going to a local show and if they're attending I'll ask but just wanted to see if anyone here knew. Depending on the cost it may be easier just to buy replacement coins.
