Thank You, Dearborn

I'm actually finding that FFD seems somewhat common on dimes after 2020. I've found mostly minor to very minor - but they're there.

The appearance of being common correlates with Schuler Presses seeing Dial Feeders installed.

The horizontal stroke Schuler Press has been the predominate Press used in the 21st century. The first Schuler Presses arrived at the mint before October, 1987 and most likely operated with a Pusher Feeding Mechanism, since Schuler was not assigned a Dial Feeder Patent until 2018. The Patent for the Pusher Mechanism was granted June 10, 1969. Dial Feeders on Schuler Presses went into use around 2018.

Circulating coin presses are primarily Schuler MRH 150 press. MRH stands for Münz-Prägepresse, Rund, Horizontal, which translates from German to "Minting Press, Round, Horizontal". 150 refers to the press's maximum coining force or capacity, which is 150 metric tons)
