Since joining this forum all the way back a couple days ago, i was inspired to look through all the coins in my collection to see if i could spot anything strange/errorish and i came across this american 1978 quarter

It has a lot of wear and im not really sure yet of what im looking for, but the valley that runs around just inside the ridge of the coin seems a bit weird (cuts through most letters in liberty deepish looking around the sides and cuts a few times into the 1 in the 1978) Sorry about the fairly large pics. still figuring out what size/details help the most.

and some fill seems to be missing, but then i dont exactly know what im looking for

If any one can tell me anything about these, or tell me im imagining things, that would be appreciated

The "valley" appears to be marks from some automated counting machine usage. If the reeding is heavily worn it could be a slot machine quarter. Just a guess from the pics.

i agree... looks it rolled around in a counting machine for a while... other then that i really don't see anything
