Manufactured by hand or by machine, marbles come in varying sizes, colors and patterns. Their manufacturing date, colors, patterns and manufacturing methods make them collectible. Learning to identify collectible marbles can be very confusing at first due to the sheer number of color combinations and patterns. You can recognize patterns and colors by viewing as many correctly identified collectible marbles as possible.

Date the marble's origination using the information gathered in Steps 1 to 3. Collect marbles made during the 1950's and earlier to gain a more valuable collection.
