What is a gold coin worth today?

As I answer this question "What is a gold coin worth today?" at 6:42 am on a Thursday on the 13th of May 2021 I see my Kitco gold live app has the asking price of gold at $58.28 per gram. You don't have to use the same app that I do. It's just one place you can go to get the market gold price. There are other apps you can use as well as just Google the price. That being said, any one of these sources gives you two of the three parts you need to determine the value of your coin.

1.Price per unit of weight

2.Weight (grams, troy ounce, dwt, etc.)

The last part of the three parts needed is

3.Purity (karats, .999, 90%, 14K)

In general, most gold coins have been around for a long time and are easily searchable online for their vital numbers like weight, purity, and measurement. There are books and coin dealers that can help you with that information too.

Now let's put the three parts together in terms of an equation.

Purity X price X weight= value of your coin

Ok, let's input some real-world numbers so we can see how this equation works!

(90% purity) X $58.28 per gram X 3.76 grams

.900 X 58.28 X 3.76 = 197.21952

Your coin is worth $197.22
