So I really like the design of the new Predator Series coins - first one being the Cougar. Having purchased all the previous Wildlife series and Birds of Prey series as well as numerous maples I am only hesitating as I am frustrated by the amount of milk spots on these coins. Is there any reason to believe that the RCM has addressed this issue and is there a possibility that the new design with radial lines will minimize the issue? For those of you who have already purchased these have you encountered milk spots?

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"

They may develop spots or they may not its hit or miss.......that being said I do have ASE with milk spots, libretads with milk spots, Phils with milk spots, Panda with milk spots, elephants with milk spots, But the majority of spots on my bullion is RCM stuff....I really like the designs so I usually only buy one of each...

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!

I heard today that if you keep a copper penny with the coins it can provide some protection - has anyone heard of this or can confirm?

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.

Quote: I think of the milk spots as an anti-counterfeit measure... I have heard this before! Someone explained to me that spotting is largely due to borax being deposited from the solution used to clean the planchets, which JGG has already explained could happen.

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.

Quote: check to see if ones in the capsules show any signs of milk spots. they might still develop milk spots. The low chance for developing milk spots have the coins, already packed in capsules - probably for their production "level above of everything" used.
