Shelving is the change (step) in height of the surface of the porcelain as you move across the sign. It is seen at the boundary between two colors, because the porcelain ("frit") is applied in layers, one color at a time. So, for instance, on a porcelain oil well lease sign, the black letters are applied on top of the white background, so the surface steps up as you move from the white area to the black letter.

As a general rule, the older porcelain signs have heavier shelving than newer ones. The height of the shelving decreased in the 40s and 50s, and by the 60s, most porcelain signs had very little noticeable shelving.

Painted tin signs, while the colors are also applied in layers, generally have very thin paint or ink, and display little or no shelving.

Beware, though, as there are fake porcelain signs with intentionally heavy shelving -- especially those from South America.

Only porcelain has heavy shelving, tin signs are painted. When I think of heavy shelving I think of almost a 1/16th of an inch lip when moving from one color to the next. Newer signs have thin shelving. Most pump plates that are recent have thin shelving so its not a 100% rule however those same pump plates if they were repo's would be even thinner. I am not sure if that makes sense...

Wes,Scott I appreciate quick response and explanation's, and at least have an idea what to look for or at, and will be aware of the repo's. I've studied the pictures of these signs when someone post's them here, which has been helpful, especially the back side. I went out an looked at my texaco signs (whick i know are real, bought from respectable old gasser's on this site), to get a feel of the layers so this helps bunch, thanks laroy

Some tin signs also have "Bumps" on them, they are embossed. A lot of the time, it is the letters or the logo that is pressed into the tin so there will be a indent on the back and an "outdent" on the front.
