Silver Rounds vs Coins

I was told that coins are not pure silver but a harder metal is added to reduce wear.
It is not recommended to use these in making of colloidal silver due to this important factor..

 

I'll give you 10 cents for every 1943 through 1945 Jefferson nickel you send me.

 

Nickel silver is not silver, it is nickel . Periodic table= N1
Know you're elements.

 

Unless you've lived it,One has to be there to see how well Cajuns band together in hard times and have a good time doing it as well.

 

I'll also give ya a buck for 1965 - 1969 Kennedy half dollars.

 

Wildbilly,you need to come by my house first,we’ll be waiting.
Have a good nite.

 

I'd be quicker to accept American silver coins. There are a couple of Mexican silver coins I could compare to what I own but that's about it for my confidence.

 

I use a scale that is 100% on the money !!
Diamond Milligram Digital Precision Pocket Scale In Case 0.001g / 10 Gram | eBay


And a way of checking thickness :
Ultrasonic Thickness Gauge | eBay

You get what you pay for !!

I purchased a scale to weigh my silver rounds when I get them. I also purchased a calibration weight. Each new silver round should weigh 31.10 grams. I weight them, check them with a very strong magnet, drop them to hear them ring and put them away. If old coins are the medium of exchange post SHTF, someone will be counterfeiting them.

 

If folks are too foolish to know that a pre-1965 coin is 90% silver then they are NOT gonna make it. If I DON'T have to spend too much time searching for their little bit of stuff AFTER they have died of NATURAL causes, I MIGHT be inclined to bury them and say a few words. Merry Christmas to You and Yours.

 

When using ultrasonic thickness gages it is important to note that different metals have different acoustic velocities. Also usually the built in velocities on some instruments are only for one specific alloy of that metal. Different alloys have different velodicites. Seriously.

 

Yes , Silver / gold / lead / and then steels & AL all have AU= 3240 but if I use my meter and I have tweaked it to 3246 to see my micrometer match the meter 100% , AG is 3600 but fine tweak is 3597 for the match ,,
Also I use ky jelly as my paste . So if I check my meter to my test sample of AU /AG I know im set to measure , Same as Weigh scale , I have a few calibration weights to set up and check the scale .

Im pretty good at this now , in the 60's these new toys were not around.
