1982 1c Zinc

A perfect quality obverse strike, unusually nice, like a SMS. Frosted design elements.

What type of scope are you using or is that a clip-on for the phone?

It just happens to have the same scratch used by the Fabricators Council based on a 1981 New York Times article. A CASS Test, leaving 15% surface un-submerged, to check for corroding outside of the stringent application.

NO

The tests you referenced are destructive tests. An incoming lot of planchets is sampled and the samples are taken to the lab and tested. Based on the results, the lot is either accepted or rejected and they dispose of ALL samples. NO samples are returned to production.

This is standard operating procedure for incoming raw materials testing in any manufacturing plant. Lab personnel can risk their jobs by not following procedures and not disposing of test samples. You DO NOT have coins struck on lot acceptance testing samples.
