you find out what the coin is made of and lk up what the density of the material is. Then measure the volume of the coin by either measuring the radius of a face, square it, times it by pi and then time that by the depth. Or,if it is a funny shape fill a bucket up to the brim with water, place the coin in the bucket. Measure how much water is left to what was in their before and u will also have the volume. Then weigh it and divide the mass in grams by the colume cm cubed and u will have the density. If it matches the density that it should be then it is real but if it is not then it is a fake

You can tell if a coin is counterfeit by checking for any irregularities in weight, size, and design details compared to a genuine coin. You can also perform a "ring test" to listen for the sound of a genuine coin, as counterfeits may sound different due to composition differences. Lastly, using a magnifying glass to examine small details like lettering and edges can help identify counterfeit coins.

Different countries use a variety of methods to make it difficult to produce counterfeit money. Look carefully at the small details of the printing and the portrait. Is anything smudged or misaligned? Is there a watermark or security thread? Does the paper feel like real money?

optoin1- you can tell if a coin is fake because if you get a coin and stand it up vertically on its sideand then tap it and then when it falls flat on its face , then if it makes a lighter sound it means its real but if its fake it should make a duller sound

option2- you can also tell by the writing and details on the edge of the coin

The simple answer is that it's not that simple. Some more crudely-made counterfeits will be the wrong weight, have a dull color, have indistinct images, or make a clunking sound when dropped. Some really bad ones have ridiculous designs, like the famous "1865 Washington quarters" that are only off-date by 80 years, or the "1851 Indian head dollars" that carry the picture used on an Indian Head cent of 1860.

On the other hand some fakes can be almost indistinguishable from the real thing because the counterfeiters take time to ensure that the weight and design are accurate. In the case of extremely rare coins (e.g. an 1804 dollar) they may go to the extent of using the same metal alloy as the real coins, simply because the profit they make selling the bogus coins is many thousands of times the cost of the precious metal used.

If you have what appears to be an extremely valuable coin, it's usually best to do a bit of research first. For example, if you have a supposed 1861 Confederate 50¢ piece it's guaranteed to be a fake because only 4 were ever made and all are accounted for. OTOH if the coin is valuable but not so spectacularly rare it's less easy to determine. In that case you may have to spring for the money needed to have it evaluated by an expert in rare coins and counterfeits.

If the differences aren't obvious simply by looking at it, a real giveaway would be the weight. You can look up the correct weight for the coin in question, and if your coin doesn't match, it's fake (though if the coin is heavily worn, it would be slightly lighter than when it was first minted).

Find the value of the coin and see if it matches close to the price they are advertising. If you find that the value is $250 and they are selling it for $20 it's not the real coin. Another thing to watch out for is if the coin(s) or advertisement says "copy". If they do it means they are only selling a replica of the coin and not the real deal.

How do you determine when a coin is silver or gold?

The easiest way is to compare the coin to a known one and look at the date, most of the time that will tell you if it is silver. For example, a US quarter dated 1964 is silver, a US quarter dated 1965 is not. Most of the time that can tell you about the coin. The next is to make sure the coin isn't counterfeit, the easiest way is to check the diameter, thickness and weight. If they aren't like the genuine coin, it is likely the coin is counterfeit and made out of an inferior metal.
