- Look carefully at the glass and pay special attention to sharp corners.

- Run your fingers along the side inside edge of the rim. You'll feel most nicks here.
- If you are buying online ask your seller to do the same checks.

I didn't ask to see it up close because there was obvious roughness on the inner rim even seeing it through the case. What is inner rim roughness and why should you care? The photo shows a close up of the inside edge of the flat rim on a Patrician plate. The plate has a sharp drop off where the rim turns into the main part of the plate and that sharp edge gets small dings and rough spots when people stacked the glass for storage. Royal Lace, Madrid, Florentine #1 are particularly susceptible to this damage. Glass patterns with rounded inner rims are much less prone to inner rim roughness; Miss America has a wide flat rim but I've seen only a few pieces with damage on the inner rims.
