Nice one. For those who are wondering what T-II stands for that would be Type 2 Planchet with upraised rim.
The large cent was minted in the United States from 1793 to 1857, with the exception of 1815. It's found the same way blank planchets are found for modern coins. They don't get minted and get mixed with the millions of other struck coins destined for circulation. It's impossible to check every single coin from start to finish during the minting process.
@SensibleSal66 Another way is that a mint employee kept a few blanks for themselves and got them out of the US Mint for their own collection.
Found this Pic from the internet. Can you imagine using steam for power back then? Just look at the guy with the cigarette in the background, LOL. Working hard do you think?
Steam engines were common for usage when large cents were made. Trains all had steam engines. Can you imagine traveling on a steam train. In the winter a pot belly stove burning wood was used to heat the car.
On December 6, 2024 I rode in a caboose that was heated with a pot belly stove but they used coal for fuel.
That is a little light when it comes to Large Cents. 164 grs is 10.63g. These weighed 10.89 grams. Does anyone know what the tolerance was for these planchets? Neat Error @Collecting Nut
