Berry Valued Member United States 394 Posts	Posted 07/26/2007 12:04 pm I was just reading in another forum that some collectors are finding milk spots on their 20th Anniversary sets. Has anyone here found milk spots on their sets? I checked two sets and both are milk-spot free. I use silica gel in the plastic bags covering the full sets and keep silica gel bags around my slabs also, found no problem with the slabs either. I hope all my forum friends have their sets in a moisture free area and are not experiencing any problems. Berry Report this Post to the Staff

Benji Valued Member United States 459 Posts	Posted 07/26/2007 1:33 pm Moisture is NOT the cause of the "Milk Spot" phenomenon. It is caused by a rinse used by the mint. So far, an acetone bath prevented my left over set from developing this? Although, I don't think anyone has come up with a definite cure? Problem free coins have been slabbed, and later the spots have appeared while in slabs. Edited by Benji 07/26/2007 1:34 pm Report this Post to the Staff
madspec Valued Member United States 376 Posts	Posted 07/26/2007 6:32 pm The best way to avoid milk spots is don't drink milk when working on your coins. The same goes for beer, you definately do not want beer spots on them. madspec Report this Post to the Staff

Berry Valued Member United States 394 Posts	Posted 07/27/2007 11:33 am Benji, What caused you to give the coins an acetone bath? Did they develop the milk spots? These spots are the precise reason that PCGS would not slab MS70 coin for years. They have now changed their minds and do slab MS70 coins for BU ASE coins, but no details if the mint has changed the process for coins they use to give the coins a rinse process. If anyone hears any news on this would appreciate a heads-up. Thanks, Berry Report this Post to the Staff

Rather, I assume that PCGS lost a huge chunk of the modern/bullion market to the other TPGs handing out MS70s. Report this Post to the Staff
