The container is a glass mason canning jar, approximately 5 inches tall (13 cm) and 3 inches in diameter (7-8 cm).

The marbles are typical sized glass aggies, about 1/3 inch in diameter (10 mm).
The jar is filled completely to the top with the marbles.

I found this jar of marbles over at my Dad's house a couple of weeks ago and took a picture of it.
How many marbles do you think is in the mason jar?
I will post the answer in one week!
