I injected a question about coin making in another thread and did not get any replies. I guess it got lost in the conversation as it related to that thread. I am just curious if there are any good videos out there on the coin manufacturing process. I have Goggled a few times but never had any luck. I would love to see some quality videos on this process.

A small mistake in that video - Issac Newton did not invent coin reeding. Reeding was in fact invented in France in the same year that Issac newton was born - 1643.

I can't remember where it was from but I have seen a documentary that shows the plaster cast and the Janvier lathe. Anyone remember it? Was it a Nova?

The US Mint site has a great explanation on how coins are made. No videos, just pictures and reading. They don't include how coins used to be made in the past. I believe they were poured into molds though. Now-a-days, they are designed, then the dies are CNC milled, planchets are stamped, then pressed with the die.
Coins have been struck on dies for centuries, even Ancient Rome used die-struck coins. Originally hand-hammered, the Renaissance and then Industrial Revolution have given us the machine struck coins of today. Many ancient coins were cast metal, however all coins used in the US have been milled or machine-struck coins. Asia has a history of cast coins beginning around 400 BC but ceased this practice in 1912. Almost all coin casting is done by counterfeiters these days. GDJMSP, can you give me further info on the invention of reeding? I know the first die collar was used in France in 1555, and it would seem that with all the references out there it would be easy to find out which coin was the first to have reeding. However, I have looked high and low and cannot find any info about the first edge-reeded coin. Thanks!
I can tell you it was issued by Louis XIII, and that it was in 1643, but as to exactly which coin it was, I am not positive. I believe it was a Louis D'Or. I'll check and see if I can find a definitive answer for you.
