There's no specific relationship between them. Silver and copper were used for different denominations of coins so the amount of metal in them depended on the coins' denominations and the relative prices of the metals.
For example, a bronze Lincoln cent (95% copper) weighed 3.11 gm but a silver Mercury dime (90% silver) weighed 2.5 gm. On the other hand a 90% silver dollar weighed about 26.7 gm.
If you're referring to US Coins of the same denomination, the answer is that the older silver coins weighed very slightly more than their clad counterparts. The two varieties are the same diameter and thickness so they're compatible in vending, counting, and sorting machines but silver, which made up 90% of a US coin's weight, is slightly denser than copper which currently makes up about 92%. Therefore a clad coin of the same dimensions will be slightly lighter.

Is silver wire a better conductor?
The best conductor of electricity is copper wire. Silver is a better conductor than copper, look up basic data. But silver is not practicable for widespread use, copper is nearly as good and more practicable for engineering use as well as cost.
Which is heavier a cube of platinum or a cube of silver?
A cube of platinum of the same size as a cube of silver will weigh more.
Which weighs more a new penny or old penny?
older pennies were made from copper and weigh around 3.11 grams while the new pennies which are copper plated zinc, weigh around 2.5 grams
Why is copper used in pennies?
Copper is a common metal, is relatively durable and the value of the metal will not exceed the face value of the coin. However, in the USA copper is no longer the primary metal in pennies. The price of copper has gone up to the point where there's more than 1¢ worth of copper in a penny, so back in 1982 the Mint changed the coin's composition to a zinc core plated with a thin layer of copper. In fact, the coin is now 97.5% zinc so there aren't copper pennies anymore.
Why do older pennies weigh more than young ones?
In 1982 US cents were changed from 95% copper and 5% zinc to a core of 99.2% zinc and .8% copper with a pure copper plating.
What would happen if a copper coin were kept immersed in a solution of silver nitrate write the word equation also?
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
A copper coin was kept dipped in silver nitrate solution for a hours or dayswhat will happen to the colours of solution?
Copper is more reactive than silver hence copper displaces silver from silver nitrate solution.hence the solution from colourless changes to blue.
What is the melt value of a coin?
This depends on what the coin is made of. If it is made of silver or gold it will be worth more than if it was made of copper or zinc.
What is the Value of a sterling silver dime from 1953?
US circulation coins prior to 1965 were made of coin silver, not sterling silver. Coin silver has more copper in it for hardness, so that the coins wouldn't wear out as fast.
Why do older coins weigh more than younger coins?
Older coins were made of different metals, such as silver or copper. Coins that used to be silver are now nickel or nickel-coated copper, and coins that were copper are now copper-coated steel or zinc.
What is the value of a 2000 Marcus Garvey 20 dollar coin?
This is not a coin made by the US mint. These coins generally have no collector value. If the coin is silver it will be worth more but if it is only silver plated with copper underneath it will be worth less.
When was the last sterling silver quarter made?
Quarters were never made of sterling silver. It's too soft. They were made out of coin silver, which has more copper in it, until 1964.
Which weighs more copper or silver?
Copper has a higher density then silver. So a cubic inch of copper weighs more then a cubic inch of silver.
What was the last year of the copper penny?
US Coins the last year for a copper (actually bronze) penny is 1982. In 1982 the penny was made as a copper coin and a copper plated zinc coin. You have to weigh them to tell the difference. Bronze cents weigh 3.11 gm and zinc ones weigh 2.5 gm. The penny has remained a copper plated zinc since 1982 however there is talk of changing it again to a copper plated steel coin. In 1943 the Lincoln US cent was steel coated with zinc because the copper was needed for ammunition during the War. In 1944 it went back the copper coin. Today the cost of copper is too high to make a solid copper coin/penny. In fact the cost of stamping/minting the coins and raw materials, the penny and nickel cost more to produce than their face value.
If copper displaces silver from silver nitrate will silver displace copper ll nitrate?
No, copper replaces silver because it is more reactive than silver, and therefore more stable in a compound.
What is Silver Nitrate plus copper?
As copper is more reactive than silver copper will displace silver and will become copper nitrate and silver is left by its own from the reaction
I know this is ridiculous BUT is there such thing as a 1966 Silver Roosevelt Dime i have a collection of silver coins and im pretty sure its made of silver Does anyone know a way to test it?
The best way to tell would be to weigh it on a sensitive balance. A silver dime would weigh about 2.5 gm while a copper-nickel dime would weigh about 2.27 gm. There have been a few reports of leftover silver planchets being struck accidentally in 1966. More likely, though, your coin has been plated for use in jewelry.
