Silly purchase, but I was curious...

I picked this one up for $12 shipped, just for giggles. It looks to have at least EF detail. Can't tell if there's any remaining lustre.

Now here's the question: would it be a candidate for crackout and acetone bath and/or NCS? I assume there's some long-term damage from the PVC?

Either way, kinda hard to go wrong at that price...

Crack it out and go with the acetone (I buy 100% pure at the Home Depot). That Blue Ribbon stuff works pretty well as a stage 2 but you should remove that with some gently soap and water and tamp dry. If that one spot has gone to verdigris you may have to go with the NCS but probably not necessary. Good price I think!

That ain't worth sending to NCS, particularly as you should be able to treat it yourself.

Funny, I thought the one thing ANACS bodybagged for was PVC. I had an otherwise lovely gem BU Dutch silver coin BB'ed by them for it, once. Practically invisible, the PVC. I never noticed it. Just a nearly-invisible film, I guess. But ANACS spotted it, and bagged my coin- no holder.

You're correct.

From ANACS website:

During the manufacturing process for soft vinyl flips, an agent is added to increase pliability. The main reason for this is to allow the flips to be reused without breaking or tearing. This softening agent will migrate out of the plastic over time, and becomes the surface film that is called “PVC Residue.” As this film continues to degrade, it eventually turns into a mild acid, and begins to attack the surface of the coin. Until the film is removed from the coin, it is usually not possible to tell if the coin has been damaged. Additionally, this chemical reaction can continue even if the coin is sealed in an inert plastic holder. This is why ANACS does not encapsulate coins with active PVC contamination.

Apparently the policy was changed at some point, as they obviously did encapsulate PVC coins at one time...

Hmmmm... Yeah, that's the ticket!
