Letter Re: Making Change in a New Precious Metals Economy
Permalink
JWR,
I did some research after reading the recent "Making Change in a New Precious Metals Economy" article. The following will make it easier to determine the metal value of coins. Thank you for your great blog.
Ounces of silver in pre-1965 coins:
Silver bullion coin = 1 ounce
Pre-1965 silver dollar = .77344 (90% silver, 10% copper)
Pre-1965 silver half dollar = 0.36169 (90% silver, 10% copper)
1965-69 silver half dollar = 0.1479 (40% silver)
Pre-1965 silver quarter = .18084 (90% silver, 10% copper)
Pre-1965 silver dime = 0.0715 (90% silver, 10% copper)
No silver in post-1965 coins:
Post-1965 clad dollar = weighs 0.260 troy ounce. (copper 88.5%, zinc 6%, manganese 3.5%, nickel 2%)
Post-1965 clad half dollar = weighs 0.365 troy ounce. (nickel plated copper- 8.33% Ni, 91.67% Cu)
Post-1965 clad quarter = weighs 0.1823 troy ounce. (nickel plated copper- 8.33% Ni, 91.67% Cu)
Post-1965 clad dime = weights 0.0729 troy ounce. (nickel plated copper- 8.33% Ni, 91.67% Cu)
Nickel coins:
Mid-1942 to 1945 (56% copper, 35% silver, 9% manganese)
1866 to present except 1942-45 weighs 0.1615 troy ounces. (75% copper, 25% nickel)
Penny coins:
1793–1857 (100% copper)
1857–1864 (88% copper, 12% nickel)
1864–1942 (95% copper, 5% tin and zinc)
1943 (zinc-coated steel)
1944–1946 (95% copper, 5% zinc)
1946–1962 (95% copper, 5% tin and zinc)
1962–1982 weighs 0.080 troy ounces. (95% copper, 5% zinc)
1982– present weighs 0.080 troy ounces. (copper-plated zinc- 97.5% Zn, 2.5% Cu)
Base Metal Content Values
(The following are as of February 2010. See You must be logged in to see this link. for updated figures)
Pre-1965 silver dollar = $12.47
1965-69 silver half dollar = $2.38
Pre-1965 silver half dollar = $5.83
Pre-1965 silver quarter = $2.91
Pre-1965 silver dime = $1.16
1971-1978 Eisenhower Dollar = 18 1/2 cents
1979-1981, 1999 Susan B. Anthony Dollar = 6 1/2 cents
2000-2010 Sacagawea Dollar = 5 1/2 cents
2007-2010 Presidential Dollar = 5 1/2 cents
1971 to present half dollar (clad) = 9 cents
Post-1965 quarter (clad) = 4 1/2 cents
Post-1965 dime (clad) = 2 cents
1946-2010 Nickel (except 1942-45)= 5 cents
1942-45 Nickel= 91 cents
1909 to 1981 penny except 1943 = 2 cents (95% copper)
1982 to the present penny = 1/2 cent (97.5% zinc)

FYI, When I saw this a few days ago on the 'Blog, I saw that the dime weight was incorrect. .0715 would be the assumed weight when one would calculating in loss due to wear of circulated coins. All the other weights listed for 90% are correct for new, uncirculated coins but not for circulated coins. The scale and your calculator are your friends when buying junk!
Someone in another post here re Survivalblog said that JRW doesn't fact check too well, this may be another example. |

1962–1982 weighs 0.080 troy ounces. (95% copper, 5% zinc)
1982– present weighs 0.080 troy ounces. (copper-plated zinc- 97.5% Zn, 2.5% Cu)
I think 95% copper pennies weigh more like ~3.11 grams, or 0.1 troy ounces...
and zinc ones only weigh ~2.4-2.5 grams |
"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen." Samuel Adams |
