    I'm not doubting your post, but I do want to confirm one point. I worked at a electrical steel lamination company. We stamped 250K-350K MT of electrical steel per year. This steel is thickness ranges from 0.014" to 0.025" We had some presses that ran 600 spm. That's lightening fast in the progressive die world. I know the coin dies aren't progressive, but I find it hard to believe they run at 750 spm. Where did you get that figure?

    I typically read most of your comments because of the knowledge you bring, so I'm very interested to get your response.

    The US Mint is now using Schuler Horizontal Strike coining presses which according to the Schuler corporation are capable of up to 850 strokes per minute (Per their website https://www.schulergroup.com/major/...muenztechnik_praegen_praegepresse_horizontal/

    From Coinage Magazine Feb 2006 The Denver Mint Today

    Schuler, the world’s only maker of horizontal-stroke coin presses, advertises a maximum rate of 850 coins per minute, but the Mint’s press operators monitor each presses’ computer screen for an average rate of 750.

    Thanks Conder101. My company had many Shuler's and Minster's. That's incredibly fast run rate. I appreciate the response.
