I think there's a faint s mark right below the 0 in the date. Is it possible? I apologize in advance for the poor quality and will try to take a better picture.
I see what you’re talking about but the pictures are far too unclear to determine anything. There’s a small chance it could be a grease filled die coin.
First, welcome to the neighborhood @Dzpyd ! It's nothing! This coin is 108 years old, and there is no telling how long it has been in circulation. There are lots of small flecks of dirt all over the coin. You're trying too hard to find something that isn't there. Chris
