I'm not sure what you mean by smooth raised edges, but I would suggest you take it to a coin dealer and have it appraised.
I have a Canadian Dime 1980 with smooth edges too but have no idea how much it is worth
A dime is smaller than a nickel. A nickel is worth less than a dime. A dime has a ridged side, while a nickel is smooth and thicker.
Assuming it's the same thickness as a normal dime, you have what's called a "flan". This error occurs when a coin blank accidentally slips into the bin with coins that have already been struck. If your flan has a smooth edge, it's worth about $1. If it has upturned edges like a regular coin but no design, it's worth about $2.
A dime has 118 grooves
10 cents, regardless of how damaged the edges are.
A blank dime planchet is worth about $1 if it does not have a raised rim, or about $2 if it has a raised edge like the edge of a normal dime. FWIW, coins are "struck" rather than "stamped". Just coin jargon, that's all.
What is 1912 dime worth
A dime is worth 10 pennies. A dime is worth 1/10 of a dollar.
If this coin is in uncirculated condition it is worth $0.25, other wise it's worth $0.10.
it's worth 1 dime.
A circulated 1939 US dime is worth about $2.70. An uncirculated US 1939 dime is worth between $9.00 and $20.00.
Your coin is 45 years old and simply showing the effects of wear and tear. The reeding on the edges is small and wears off faster than the rest of the coin's design.
