Strange Mint item ? Or NOT ?

10 posts in this topic

Looks like a cut section from a bar of cold rolled steel with a Birnell Hardness Test done to it to determine carbon content/proper heat treatment. The very center of of any formed steel will be the weakest. During production and subsequent heat treatments, impurities migrate to the center, that why it appears that there is an impression dimple there. I don't think this is mint related...


But then again, I'm one of those "self proclaimed Experts" who knows everything there is to know about, but yet know nothing.


There is some discussion here:

Your both correct, Dremel makes an engraver (electric) but I would say that the letters & numbers have been engraved by a high speed pnematic engraver, one where the stylus vibrates up and down and peens the surface rather than trenching.


Carry on
