For any type of collector, certain pieces are worthwhile for collecting, other pieces aren't. Here is a guide to collecting antique license plates.
Of course, if you happen to own a vanity tag of a famous person, this plate could be worth a lot, but for ordinary tags, things to look at in the way of value are: the year the plate was issued, whether the plate is smaller or larger than most normal tags, the materials which make up the tag, such as porcelain or steel and whether or not the tag is rusty or faded. Other collectors' items are bicentennial plates, plates which show the state seal, judge or judicial plates, plates with funny or bizarre slogans, plates that display the map from that state and plates which show exotic birds or animals. If you collect only plates from a certain state or country, you'll want to fill your collection with a plate from each year, all special issue plates, plates with the queen of that country's picture on it, or any governmental plates you may be able to attain.
As for locations to find antique license plates, Grandpa's garage might be one place to start looking. Often, license plates were changed, with the new one being attached to the car and the old one tossed aside in an outbuilding. And, dozens, if not hundreds, of old tags can be found at junk yards, but usually these tags are damaged beyond worth. Online auctions are a great place to find license plates from another state or country. "This and that" country stores may have a surprise awaiting you; these places are known for having some very old, very interesting collectibles.
There are also many web sites where other collectors offer to buy, sell or trade their plates. Flea markets and yard sales are additional ways to hunt for old license plates. Be well-schooled in spotting tags which have been altered or touched up, so as not to spend good money on a worthless piece. Dents, even small ones, or scratched paint can bring the value of your collection down, so look closely for marks of any sort before purchasing. Storing license plates doesn't require an intricate set up, but does require a good amount of space if you have a large collection. Some collectors keep their antique license plates in display cases, whereas others store them in boxes. Moisture and sunlight, a license plate's two worst enemies, should be kept away from the plates, preventing them from rusting or fading.
For further protection, some collectors wrap the plates in bubble wrap, then box them, or keep them in individual zipper-lock bags. Some collectors oil the plates somewhat to further prevent them from rust and deterioration. Don't store the tags one on top of the other without something in between them to keep scratches from occurring. Catalog your collection as it begins to mount, to prevent you from purchasing duplicates or to make you aware of which ones you can afford to sell or trade. If your collection has several very worthwhile pieces, it might not be a bad idea to insure them against fire or theft. Check your local library for books about license plates, which cover everything from the uniqueness of certain ones to where you can join clubs and meet other collectors.
