Are you asking about melt value? $1.187 approx. according to coininflation.com. The figure is for melt value only. You would need to minus handling fees, etc. Now, this is assuming that you are speaking of an old rough circulated dime. If not, then that would be a different story. I suspect that we are not talking about a proof here. I am not an expert, just a lady that likes circulated 90% dimes. Barbers and Mercuries are my favorites. I do have a few recent Roosevelt Proof dimes - they are worth more than $1.187 each to me.
At today's silver price, $1.1899....as stated, this is melt value for a circulated dime. AND, welcome to the forum!
Would depend on condition, odds are the dime you are looking to buy or have is circulated, and is worth around what has already been said here in the posts above.
