To determine the value of 11.4 kilograms of current copper coins, you first need to know the specific coins in question, as their composition and weight can vary. For example, in the UK, the one-pence coin is made mostly of copper and weighs 3.56 grams. This means 11.4 kilograms would contain approximately 3,200 one-pence coins, which would be worth about £32.00. For accurate valuation, check the specific coins and their current market value.
If you refer to the scrap value of the copper, there is no copper in British "copper" coins these days.
1 kilogram of pound coins is equivalent to approximately 109 coins, so 3 kilograms would be around 327 coins. As of 2021, one British pound coin is worth 1 GBP. Thus, 3 kilos of pound coins would be worth approximately 327 GBP.

If "olden days" means "when the coins were new", the answer is that like any circulating coins at the time, they were only worth face value. The only 2 pure copper coins that the US issued were half-cents and Large cents, from 1793 to 1857. Of course at that time they had far higher purchasing power than similar denominations do today. Both coins were discontinued in 1857. The 1¢ coin was downsized to its current diameter of 19 mm. Initially they were made of a copper-nickel alloy but after a few years that was changed to bronze, which was 95%-pure copper.
These coins are common and are worth about 2 to 15 cents in circulated condition.
Coins in average circulated condition are valued at 3 to 10 cents. Uncirculated coins can be $15.00 or more.
Lincoln Memorial cents minted between 1959 and 1981 are all worth about 2 cents for their copper content.
