I have been reading this thread and seems to me alot of overreacting going on. If the coins are labeled as BU, it would not be cool to have fingerprints. But milk spots? As I understand, no way to avoid sometimes even if stored carefully.
Then I checked EU Mint and this is what I found:
2016 1oz £2 GBP UK Silver Britannia Coin Privy Monkey Mark
Grade: Uncirculated (Some coins may have spots)
Note: this coin is slightly circulated, it may have spots and/or scratches.
I do not see where is the problem. It's a bullion. Silver content is there. Want clean bullion? Pick BU. Pay the same or more, depends on a dealer not on your perception.
Plus, we still have not heard if they replied with an answer which i am sure they will do.
I feel it is a shame to trash a dealer this way. I have only one purchase with them, everything went perfectly.
Good job EU Mint! Keep it up!
