You have a Liberty Seated Half Dime - a 1869-S coin in good condition (G4) is worth: $20.00; if its mint state is MS60, the value increases to: $400.
The 1969-S dime is a Proof coin, that's why it has higher value.
The 1863-S half dime has retail values of $23.00-$40.00 in low circulated grade, $60.00-$110.00 mid circulated grade and higher grades are $312.00-$432.00. I do suggest having it graded by a collector or dealer for a better idea on value.
dime = 10 cents
No rare 1941-S dimes. The 1941-S Mercury dime does have large and small mintmark varieties as do all coins (except the half dollar) that were struck in San Francisco in 1941, they have no added value.
About $25 in G-4 condition, $60 in F-12, and $135 in VF-20.

The difference (and the value) is where they were made. S= San Francisco, D= Denver.

Please check your coin again and post a new, separate question. No half dimes were minted at San Francisco until 1863.
