Unfortunately the supply of damage-free Roseville Pottery has declined over the years when most collectors prefer their pottery in mint condition to get the highest value when appraised at antique shows.
This means that minor factory related damage will not depreciate the value of your pottery.
The hardest to find forms of mint pieces of Roseville Pottery are the Sunflower, Baneda, and Futura due to the high demand.
Mint pieces still command the highest value at antique shows but it is understood that there just aren't that many mint condition original pieces and most production generally stopped in the 1950's.
Examples of the pottery vary greatly in terms of flaws, damage, color, style, you name it.
While its obvious that the most perfect and flawless pieces will generate higher values than others; style, color, and good molding are subject to the antique store or road show appraiser's values in terms of what they are looking for.
Most collectors prefer strong, rich bold colors and detailed molding designs and patterns.
This of course, is subjective as well.
Flaws that will depreciate the value of your Roseville Pottery piece include, but are not limited to: extensive glaze pops, excessive crazing and peppering.
Many of the tradeshows however, expect crazing as "standard" on all factory made pieces.
Cincinnati Art Gallery, David Rago and Treadway Gallery are the appraisers that expect this as part of the process.
Beauty of the pieces is truly in the eye of the beholder and cannot simply be judged based on color, or glaze quality.
What one may think is cracked glaze, another may appreciate as "character" or a unique-ness to the piece.
Collectors should focus the most on seeing their pieces as an investment and treat them as such to avoid depreciation factors that can come from misuse, improper care.
Most appraisers do consider minor factory related flaws as non-depreciation factors but color glaze and detail of molding is subjective and specific to each individual piece.
