How much is a 1925 dime worth?

1925 is not a rare date for Mercury Dimes.

In average circulated condition, it's worth about a dollar.

If only very lightly worn, it's worth about $5.00

A nice uncirculated one is worth about $50.00

If there is a "D" or "S" mintmark on the back (at about 7 o'clock near the rim) then the values will be significantly higher:
