Assuming the coin is circulated, the 1871-S Half Dime is a better date coin. For an accurate assessment of value the coin needs to be seen and graded. In general retail values for low grade coins are $15.00-$40.00, better grade are $45.00-$90.00 and coins showing almost no wear run from $145.00-$230.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer.
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.

1951s Dime retail is $1.00-$2.00 depending on the grade
The difference (and the value) is where they were made. S= San Francisco, D= Denver.
A proof coin has a retail value of about $1.00
A 1903-S Barber Dime in good condition (G4) is worth: $85.00.
August 21, 2009 The 1983 no "S" dime proof set has a value of $1000.
Please check your coin again and post a new, separate question. No half dimes were minted at San Francisco until 1863.
