I'd research and try it. It's a great lamination, attached and detached but that corrosion will only get worse.
This coin came out of an old wheat roll that was stored for a long period of time,after opening the roll.... most of the coins started turning green after being exposed to the air..I was quite disappointed
The term "lamination" needs to be changed. Metallic separations on alloy coins should be a "delamination"; if still attached, it should be a "retained delamination."
I'm using it as a general term...Lamination error...an error occured during the Lamination process.. whether it be a Delamination,retained Delamination ect...its still a Lamination error...imo
I know they use the term, but it is not really accurate in a linguistic sense. It is the same as saying you are wrapping a present when in fact you are taking the paper off.
