Milk Spots On Silver Maples

Silver Maples are known to have milk spots sometimes. But in 2018 the Royal Canadian Mint started using what they call Mint Shield process to reduce milk spots. It seems to be working. There can be milk spots on Silver Eagles too but not nearly as often in my opinion. The British silver Britannia can have milk spots. I bought ten of the new Britannia with King Charles III and one had a huge milk spot.

If you use your internet browser search line or YouTube search line you'll find out lots of info about milk spots on silver bullion. Some don't mind them, others do. Some claim you can clean off milk spots, others say don't try it or you could damage the surface. I don't like them and sent the spotted Britannia back for exchange. Here is pic:

Maples seem to spot a lot worse than Eagles until the mint shield was added
The worse years for the US Mint was when bullion production took off, the same years that they cancelled the proof and Uncirculated, 2009-10 and even a few years after that. Planchet quality issues.
