2013 Canadian Polar Bear /Elizabeth II bullion coin, weighing 1.5oz. As with all coins, especially silver, some milking will occur, even in graded coins. This is a natural process that sometimes takes years to show. It is due to the manufacturing process. The Royal Candian Mint is known for this occurrence.This DOES NOT affect the value of the silver bullion. As with 99%+ of Silver minted coins some milking will occur on older coins. Milk spots form from the annealing process.
Annealing is one of the final processes the silver goes through when manufacturing a silver coin. This process is a system of baking and cooling the coin in order to prevent the silver from becoming brittle. Unfortunately, during this process, borax can be left behind on the surface of the coin and end up baked into it.
Exposure to this chemical is reportedly due to cleaning residue left behind on the dies that strike the coins. This is due to the mint manufacturing process.
These are NOT perfect specimens. While they are directly from the depository, they are mass produced and may contain spots or marks due to manufacturing. They have NOT been touched with bare hands, ever. Also the coins will be protected by a hard plastic sleeve. I will also include 10 Air-tite plastic holders.These are beautiful coins that display nicely. This item is in the category "Coins & Paper Money\Bullion\Silver\Coins".
