As a practical matter, Indefinitely. There is people that have used coal they have found in cellars that was easily 50 years old. You could probably let it sit there for thousands if not millions of years.

Coal doesn't absorb moisture or breakdown too much, so as Richard said, quite a while. Coal been in the ground for ? Millions of years? what a few more.

Have to check the expiration date on the bag.jkabdoors wrote:How long can bagged coal be kept before it has to be used?
j/k of course. It doesnt go bad.
Anthracite is approximately 300,000,000 years old so chances are you should be good. But if you stack it just right you may run into the trouble of some of it turning into diamonds in a couple hundred million years....

It was in the ground for about 300 million years. However once mined and exposed to the air, it will deteriorate rapidly. My guess is it will not last more than 1-2 hundred million years. Couldn't help myself.

When I told my 9 year old daughter the coal in the basement was 300 million years old, her eyes got wide and she said, "wow that must be worth alot of money, you shouldn't waste it by burning it in the furnace!!!"
