First, weigh your coin jar. You can use a standard scale that you would use to weigh yourself with. To get more accuracy we suggest that you calculate the weight by stepping on the scale holding the coin jar and then again without it. You then subtract the second number from the first number for the coin jar weight. You should also make an estimate on how much your coin jar weight would be if it was empty and also subtract that from the total weight of the coin jar.

Second, grab a representative handful of coins from the jar and count how many of each coin you got in your handful. Make sure you get a good random mix of coins that reflects the mixture of coins in the jar. Then fill in the values below and click the "Submit Form and Get Estimation" button.
