I have an extensive collection of the RRP Pottery. This includes the shoulder bowls,(8 graduating in size) crocks, ramekins, salad & soup bowls, dinner plates, salad plates, coffee mugs, tumblers as well as casseroles and lids pasta bowls and as well as a wash basin and picture, and also a 2 gallon cooler. The pattern is the natural color with 2 blue bands as I am under the impression is called Williamsburg. All pieces are either stamped RRP, Roseville or etched. All are in mint condition with NO cracks. Any info I can get on this would be greatly appreciated. I am cataloging this for insurance reasons and would like to have some input on the worth of the collection.

With regards to the insurance, or replacement value for your collection, it is probably best to consult a professional appraisal service within your area. You can probably find one your phone book's yellow pages, or the internet. Your insurance agent should be able to help you, also.
There may even be a professional appraisal service outside of your immediate area, who, for a fee, would be willing to send you detailed information and replacement value.
While participants of this forum are always eager to help, for someone to even hint a monetary value on your items here(even if you posted photos),the figures given may be construed as subjective(as well as erroneous), at best. Thanks. Tim

Thanks Tim for your input on this I should have realized what I was asking was not feasible.
I do have a couple of other questions though. How do I know which is the older pieces?
Some are stamped with the RRP, Roseville, Oh mark and some are etched. I am assuming the newer are etched as I did buy some at small shops as far back as a year ago. But this pattern has just gone scarce except for the small crocks the market has been flooded with. Also were there any salt and pepper shakers or butter dishes and the likes of the smaller items made? I do have the small creamer but would like a sugar bowl to go with it. I have seen on EBay a 9/13 baking dish but lost the bid. If anyone has any info on this pattern please let me know?
Thank you for all your expertise on this site. I greatly appreciate it.
