I think this may be the answer...
Not sure about the thickness that is mentioned but this guy is getting them re-coated. They've been on ebay for ages & he openly admits to this practice. Whether what he says is true or not I a not experienced enough to judge so I'll let the experts do that. The seller ID is silver_strikes_australia. I don't do strikes so have never dealt with this seller before.
Here's his auction details
I WILL BE LISTING THOUSANDS OF SILVER STRIKES.
MOST CLAD STRIKES WILL BE LAYERED WITH GOLD OR SILVER TO MAKE THEM MORE INTERESTING.
I WILL ALSO LAYER SOME OF THE OLDER STRIKES.
IF YOU WANT ANY PARTICULAR STRIKE TO BE LAYERED WITH GOLD OR SILVER JUST SEND ME A MESSAGE AND IF I HAVE IT AVAILABLE I WILL LAYER IT WITH GOLD OR SILVER.
AFTER I HAVE SOLD ALL OF MY $10 I WILL BE LISTING MY $40 AND $200 STRIKES.
I TRAVEL TO VEGAS EVERY 4 MONTHS SO WILL BE FAIRLY UP TO DATE WITH THE LATEST RELEASE STRIKES AND WILL BRING BACK BETWEEN 20 AND 50 OF EACH AND LAYER THEM WITH PURE GOLD OR SILVER.
and some links to sold strikes
