Sorry no US 20 cent coins dated 1802
The U.S. did not mint 3 cent pieces in 1802. Silver 3¢ coins were struck from 1851 to 1873. Copper-nickel versions were made from 1865 to 1889.
how much is silver 50 cent piece dated1936 worth
between $50.oo t0 775.00 depends on condition
About $2.00 only for the silver.
Its value is 50 cents and has no silver at all in it.
1966 Kennedy half dollar is 40% silver and valued at about $2.50 for the silver.
Look at the again, with a date of 1854 it's not a nickel three cent piece, it should be a silver three cent piece. Post new question.
The Silver value is $3.05 as of today 3-22-10
A 1962 half dollar is 90% silver. The circulated value is $7.01 because of the silver content. The uncirculated value is $20.
Unless you find someone that wants it the value is just for the silver.
If it shows any sign of ware at all the value is for the silver only, that's about $1.00
1965-1970 Kennedy half dollars are 40% silver with a value of about $2.00 for the silver.
