Inner Rim Roughness - Bane of Rimmed Depression Glass

You'll probably find listings online for depression glass with IRR, inner rim roughness. While only you can decide how important this is to you, many of the patterns with squared off rims are plagued with this.

The bowl shown here is the cereal in pink Adam depression glass by Jeannette. Adam is one pattern that is very difficult to find mint, with no damage whatsoever. You can see that the rim is square with the vertical sides of the bowl, making a fairly sharp corner. When pieces with these sharp corners are stacked, they get tiny nicks. Often the nicks are not visible and you will find them only by zealous checking. But it's more common in my experience to have nicks that don't show up easily to the eye but are easily felt.

This bowl is a case in point as the seller assured me it and the other three with it were free of any nicks. Unfortunately all four bowls have IRR, ranging from minuscule to quite evident. Needless to say the value is far less, anywhere from 25 to 75% of what a mint bowl would be.

I recommend that you always ask sellers to recheck pieces. While this is no panacea, it is one more chance for them to find problems. Personally I check when buying, when washing, when listing and when wrapping and it is simply amazing how easy it is to discover a problem only when wrapping! It is disappointing and embarassing to find a problem only after the sale!
