Question Regarding New Series Of Bullion From RCM

From my recent experiences, no. I had a tube of 2015 half-oz Bald Eagles go milky in a matter of months. The laser etched striations had no effect on stopping the spots.

Really wish the RCM would fix this - never had any milk spots on my American Eagles, Philharmonics, Koalas or Kookaburras.

The rule that works for my coins:

99% no milkspots for coins distributed in capsules - Koala, Kookaburra, only Panda may have small ones.

Milkspots will appear on majority of SMLs and other RCM bullion (Reverse Proof or BU)

I have couple of Elephants with milkspots and one ASE, and couple of Philharmonics coins with large "fogged" areas, but this whitish area seen very well in some angle.

So....for me it is "capsule = no spots"

I once saw somewhere that RCM considers these coins as bullions and therefore have no intention on doing anything about it. I guess putting them in air-tites would help.I have a couple of sealed tubes and only hope for the best if I ever want to resel them!

Pure elemental silver is generally reactive and will form inorganic compounds on the surface of the coin. Any rinsing agent used in the coin manufacturing process that contains: nitrogen, water, sulphur, acetone, alcohol or phosphorus will cause spotting. The reaction may take years, but if any contact is made, spotting will occur. Surface reactivity is greatly reduced by introducing a hardening agent, such as copper to stabilize the coins surface. Basically, reducing the purity of the coin by adding copper will reduce the spotting issue/occurrence.

Thanks for all the info. I may still pick up a few and make sure they straight into airtights. That being said I plan to go back into my birds of prey series and check to see if ones in the capsules show any signs of milk spots.
