MS63, the bottom of the bell is just strike weakness and the numerous small ticks around the ear and hairline are also attributable to strike weakness. I suspect those marks are not from banging around with other coins, I think they were on the planchet before striking. Most blank planchets look pretty beat up but the marks are obliterated when a coin is fully struck. If the coin is weakly struck, you can see these latent marks and I suspect that is the source because the fields are actually very clean.
Overall, a nice key Franklin
