An original porcelain sign can be a valuable collector’s item and even be a profitable investment. These signs were made in the early 1900’s using a durable enamel coating over metal which allowed them to withstand the elements. Companies like Coca-Cola, Texaco, and Mobil paid for the manufacture of these signs in order to advertise their products prominently. The signs became so popular that they began to be collected by people who wanted to own one or more of these historic advertisements.

The first step in determining if an authentic porcelain sign is real or fake is a thorough inspection of the piece. When companies initially started having these signs manufactured they enlisted the services of professional porcelain enamel sign makers to construct and paint their symbols of advertising. The way the porcelain enamel was laid out will show the difference between a genuine sign and an imitation in most cases. For example, all lettering on a genuine sign will be straight with absolutely no wavy appearance. Reproductions, on the other hand, will tend to be curvy in appearance.

Another important factor is examining the porcelain’s shelving. This is a characteristic that can be seen with the naked eye or by using a magnifying glass. The shelving is a layering of different colors that are applied to the sign. If the piece is genuine you should be able to feel the different layers by running your finger over it. Reproductions are not usually layered in this manner.

It is also essential to check the condition of the sign. A good sign will have no crazing or etching in the finish and should still be shiny in appearance. A sign that has been restored or doctored in any way will be a fake and should be avoided.

Lastly, it is essential to know the history of the sign. A porcelain sign that has been altered in any way may be a reproduction and should be avoided. Reproductions are not usually marked as such, so it is up to the collector to examine a sign closely in order to determine if it is real or a reproduction.

Fake Porcelain Signs

It is not uncommon to see fake porcelain signs sold in the market today. These are typically found on eBay, Craigslist and flea markets. It is not unusual for a collection to have 90% authentic signs and 10% reproductions. It is also not uncommon for a seller to sell a sign and then “age” it so that the buyer believes it is old. This type of deception can be done in many ways and it is important for a collector to examine a sign carefully before making a purchase. It is also important to look for a trustworthy seller that will be willing to answer questions about the sign or provide additional photos and information about it. Many sellers will have a way to tell you if a sign is genuine or not.
