One major variable: What is the date? If you have a acid restored 1915 s it's going to have a much different value than a 1936. You can also get a doubled die 1916 or a 1918/7
I have a bunch, here are just some of the earlier ones: 1913v1-4 1913v2-2 1913Sv1-1 1913Sv2-2 1914-7 1914S-1 1915-5 1915D-3 1915S-2 1916-15 1916D-4 1916S-2 1917-17 1917D-2 1917S-2 1918-9 1918D-2 1918S-3 1919-7 1919D-1 1919S-2
Post pictures of the 1915 S That is a key date and will have value even if it's acid restored. Also if you have 1913 type 2's post pics of those as well as that is a desirable date.
Numismedia lists the 1915 S at $38 in G4 condition. Since yours is restored it would be less, I can see it going for around 12 dollars or so. We'll see if someone else comments. Any pictures of the type 2's?
You're right. It's my fault for not noticing the mound on the type 2. If that is a real 1913 s type 2 they go for $250 in G4. Unless I'm missing something I would say that coin is worth at least $85
