Does current generation FFD only affect the anvil die?

My census shows that both dies may exhibit Feeder Mechanism Die Damage beginning in the 1950s.

Today the Reverse Die is the Hammer Die and the Obverse Die is the Anvil Die. Shuler Presses have been used since the mid 1990s and all Schuler Presses have this inverted die installation, according to the US Mint. Most Schuler Presses are horizontal stroke with only about 4 of the Philadelphia Schuler Presses with a vertical stroke installation.

2020 D 10c fits the bill with horizontal orientation scrapes. No struck through features though.

Got another LWC example for you Pete.

This looks like the same degree and direction as the 57D I posted earlier in this thread. https://goccf.com/t/483763

Excellent example! This will be the only 1955 example I have for my census!

Thank you!

If I had known about this a month ago, it might have been a candidate for inclusion here:
