Copper plated zinc information.

Found this on the web and wanted to post before forgetting. This company plates US coinage according to their PR.
Jarden Zinc Products .

I haven't even had time to search the site. So have fun while I'm off working today and let us know if there is any useful info here.

Pretty interesting info Cliff. This company made the zinc lids for "Ball" Mason Jars back in the 1800's, now they are plating blanks and doing all kinds of things!

Cool site... I did notice how they talk up the zinc as corrosion resistant and wear resistant http://jardenzinc.com/coinage/why-jarden-zinc to bad the frankenzincs didn't get that info

Yep, It's all about the marketing!

I've always wondered why zincolns don't wear much.
It can't only be the zinc because I never see them with the plating worn off the high spots from honest wear.
Other than they don't get used much and live in coin jars I don't see a reason.

Check out the "Pressroom> Resources> information" by clicking on each subsequent page of the main website.

Here is a wear test they performed.
TEST .

And if you look in their "History" timeline ("Our Company" heading), they state "1998-100% Supplier to the U.S. and RCM mint"

Interesting that the chart did not show copper plated zinc!!!

Coin World must have been reading this post.
See this LINK . Would love to find one of these.

Edit: Interesting to note the Northeast to Southwest lines on the Zinc core in the link above. The lines show up on the plated cents we find. This may account for some of the other anomalies we see like the struck through rim burr that have no evidence of a burr missing. If it was struck through in the "shaping" process for the zinc core and fell out before being plated.

Is there a category of mint error for defective planchets before plating? (similar to defective planchet before the strike) Thanks for any insight.

That's cool... Thanks for the link... Not sure if there is a category for pre plating errors other than the roller lines which is what appears to be on that zinc core!!!
