Things You'll Need
Instructions
Purchase a book about identifying sea glass such as "Pure Sea Glass," by Richard LaMotte or the "Sea Glass Hunter's Handbook," by C.S. Lambert. By learning to identify the more valuable finds, you can determine the best market for selling them.
Sort your sea glass by color, type and shape. Use your identification book to help classify the pieces.
Visit the local library to research whether a glass works or garbage dump ever resided in the town or near the beach where you found your sea glass; this can increase the likelihood of your pieces being historical sea glass. Buyers of sea glass like to know the history of the sea glass they are purchasing.
Sell sea glass at farmer's markets or craft fairs in your area. Contact the organizer and ask what the requirements are for setting up a booth. Arrange the glass in attractive groupings by color in small baskets or jars. Be willing and able to talk about the history of sea glass and its significance to the local area.
Create attractive jewelry, such as necklaces or bracelets or earrings, with your sea glass and take your wares to local craft shops to sell on consignment.
Develop an online market by creating a website or selling at online auction sites. Use a good quality digital camera to take clear, representative photographs. Serious collectors of sea glass will be scrupulous in their assessment.
Join a group dedicated to sea glass collecting such as the West Coast Sea Glass Association or the North American Sea Glass Association. These groups sponsor art events and festivals where collectors can meet and mingle. NASGA puts on an annual festival where vendors can sell their wares or submit their best find in the "Shard of the Year" contest.
