Barber Dime known S/S?

Not my coin. Taking some photos for a friend getting them ready for sale.
During the process of taking photos, I'm also learning at the same time. I also see some other stuffs on the coins as well.
Photo below is from 1905 S Barber Dime. Can't show the entire coin pics but this could be a cool error/variety. I've looked and can't find any reference to compare with.

You may want to reach out to the Barber Coin Collectors' Society (BCCS). They have published a complete variety survey for Barber quarters and have one that appears completed, but isn't labeled as such, for Barber half dollars. There might be information for Barber dimes that hasn't made it to the site yet.
