lemme try, even though some of my bro's here know more:
first go to this website:
http://www.coinflation.comevery pre 1965 Half dollar, Quarter and Dime contained 90% silver, which means that a roll of $10 FACE value contains 7.15 to 7.23 troy ounces of Silver....the Halves and Quarters are in $10 rolls, 20 Halves, and 40 Quarters, the dime roll is $5 face value and contains 50 dimes.
coinflation.com has a silver value calculator.....scroll down, you'll see it. click on it and its easy to use. Just start to remember the amount of silver in these individual American coinage.
in 1965, LBJ stopped this practice, but the Half dollar Kennedy continued to be minted with a 40% silver composition, from 1965 till 1971. Tricky Dick stopped this in 1971, guess he figured he's pay his old nemesis back, i dont know, i'd ask that human hyena, but he's probably drinking lava hot bitumen down in hell with bezalbubb, so....thats a no go.
theres one more 40% silver composition coin worth a look and thats the UNCIRCULATED Eisenhower Dollar, but you have to be really careful, the Brown and Blue Ike Dollar is 40% silver, but remember this, all CIRCULATED Ike's minted are just "clad" coins, meaning they have no silver...its only the UNcirculated and PROOF Ike's that contain Silver. There's a lot of tricksy folks out there, and the way to tell is two fold, if they advertise, or you see a "circulated" Ike and they say "silver"..stay away, the other way is to take a digital scale, the clad IKE is 22 something gram, while the REAL Silver Ike will weigh out at 24.6 grams, but dont freak if you see them at 24.1-24.2 gms.
so if i quote you a $10 face value roll of pre 65 American coinage and say "i'm offering this roll at 30 times face", that means i'm asking $300 for the roll...thats roughly where the market is TODAY...and you do the math, 300 divided by roughly 7 oz's is about $43 to the ounce, which is $3 over the Comex board...regard the Comex board with suspicion, its a cooked mkt, and doesnt really represent real world prices...you can go to bullion direct....go to their "nucleo exchange", click on that, then click on silver, scroll down and you'll see various submarkets including 90% coinage, with a bid and ask.
hope this helps, AND start NOW, to go to your banking institution and ask for $100 boxes of nickels, and start stacking them at home. Each nickel is now worth 6.7 cents and sooner rather than later will be debased...so good luck and God bless you, neil
ps...if they look at ya funny at the bank, just tell them you're doing "youth bingo" this weekend, roll your eyes at this 'burden' and hope you wind up with a good teller, dont let them charge you a premium to get YOUR money OUT.
