Hi all, I wanted to share my latest Mint Error acquisition. It's a beauty! 1 Cent - 1939 S Mint MS 65 Red With Occluded Gas Bubble on the Obverse - Planchet Error (Hard to see but it's located under LIBERTY) From the error-ref.com website Quote - "Definition: On rare occasions a pocket of gas forms and expands when a planchet is struck. The heat generated by the strike is deemed responsible for the gas expansion. The expanding gas pushes up the overlying metal, producing a rounded bulge with soft borders. If the roof remains intact, the error is designated an “occluded gas bubble”. If the roof explodes from the internal pressure, we call it a “ruptured gas bubble”. By definition, occluded gas bubbles are generally restricted to solid-alloy issues. While gas bubbles are sometimes seen on clad coins, these always turn out to have been caused by heat applied externally outside the Mint. Occluded gas bubbles should not be confused with blistered plating, the latter being an affliction restricted to copper-plated zinc cents." Closed quote I want to share these images with you -
That's a nice different kind of Mint error Paddy. Thanks for sharing and adding an error I need to find. lol
Piling on! https://www.cointalk.com/threads/1946-lincoln-cent-occluded-gas-bubbles.330943/#post-3310291
I don't think that would be an Occluded mint error. What you have is a bubble that was created due to extreme heat. It is damaged.
