About a dime.
I have a Canadian Dime 1980 with smooth edges too but have no idea how much it is worth
10/25 = 2/5 = 0.4 = 40%
Divide the value (in cents) of a quarter, by the value (in cents) of a dime. Alternately, you can also use the value in dollars in both cases.
10/25 = 2/5 = 0.4 = 40%
Your coin has been chemically altered -- like with acid -- and has no added value.
No pH value, cf related questions on pH of dime-quarter-penny
In good condition, I've seen 1949 quarters sell as high as $9.99.
Quarter (25) Dime (35) Dime (45) Dime (55) Nickel (60) Penny (61)
You might go to PCGS.com or get a copy of the coin Red Book. Hope this helps
Quarter= 25 cents Dime= 10 cents
A quarter is worth 25 cents, while a dime is worth 10 cents.
