If you have the time, you can begin with reading several books on vintage costume jewelry as well as search the Internet, browsing to get a feel for your items. The library will have some books and be sure to check the library's reference section.

All things considered, prices vary due to geographical location, condition, fashion and color trends, designer signatures, and rarity. When you are ready, you can box your lot and head to a local antique dealer or antique mall.

You can also contact an online dealer. Visit their website, read the "About us" section and any testimonials, to get a feel for the person.

Contact the dealer, and inquire if they are interested in buying your items. You will need to show your pieces to the dealer. This can be done a few ways:

1. Scan the pieces front and back
2. Take clear, well-lit digital camera close-ups front and back
3. Send the lot for dealer inspection or
4. Take clear close-up photos with a 35-mm camera and send the photos or a CD with the images. Again, front and back, well-lit images shot up-close.

What the dealer is looking for is condition of the piece including plating, prongs, and rhinestone clarity. Be sure the images show these things. It is best to shoot the pieces on a lighter colored fabric- light gray works well.

Inform the dealer of any signatures or markings on the backs of the pieces. You will probably need to view your pieces under a bright light with a loupe. State your asking price. A vague, "I do not know what it is worth, what will you give me", is not recommended.

If you have absolutely no idea what the value is, it is fine to ask for their best price but, then, it is not recommended to counter with an amount after they gave you their "best price". Rather, you could ask what their best price is, and that you would like to get at least "X" amount. If you have contacted several dealers, take the best offer.

Another option to sell your vintage jewelry is consignment. Many dealers offer consignment. You can request information regarding their terms. Typically, you get more money for the items that sell on consignment. This route can take longer, as you wait for the sale.

Following these tips should help get you the best price for your vintage costume jewelry.
