1.) Die impressed, ROZANE, or / and RPCo*, and a series of numbers indicating the type of ware, and its shape, (this was done often on Roseville Pottery pieces from 1900 to 1904, and after the mid 1930's). 1900-1904. See note under Roseville Pottery mark #2.
2.) RPCo in a banner - Roseville Pottery mark as a paper label. 1900.
a.) Pieces marked “RRPCo”, or “RRPCo Roseville, Ohio” were made by Robinson Ransbottom Pottery of Roseville, Ohio, and not by Roseville Pottery. Many of these pieces were made in the 1970's and 80's and are being sold at many flea markets and antique shops as Roseville Pottery. b.) "R P C O" was a mark used early at the Rockwood Pottery - Roseville's is die impressed, and Rockwood is incised.
3.) Red circle with white inward triangles in the circle border circle - paper sticker indicated stock number & retail price.
4.) Die impressed, AZUREAN, or AZOREAN RPCo. 1902 -1904. This seal was often used with other Roseville Pottery marks, and can increase a piece's value by 25%, or more.
5.) Circle label with cursive words "Hollywood Ware" used on many Rozane pieces with fruit or flowers. Roseville Pottery mark as a Paper label. 1906.
6.) Circle with the words "ROZANE WARE" in the foreground & a rose in the background. This Roseville Pottery mark was also known to have a chevron below the circle with a line name in it. It is a ceramic or paper applied (label) seal or wafer. 1904 -1906. Seconds had the seal removed - Sold through Roseville's outlet. Line names on these include: Egypto, Mara, Mongol, Royal & Woodland. The paper label is by far very scarce.
7.) ROZANE "OLYMPIC" POTTERY - Black ink stamp. 1905.
8.) Black, brown, or blue ink stamp - Roseville Pottery mark in a circle shape forming the words "ROSEVILLE POTTERY" and the words "ROZANE WARE" across the middle of the circle. 1917. a.) Make sure this Roseville Pottery mark is under the glaze, many fakes have the mark rubber stamped, with acid over the glaze. b.) Another fake of this Roseville Pottery mark is the spelling “R” “U” Zane. The “U” is made to look like the “O” of the original with ware on the top edge (see Roseville Pottery mark 8b on left). c.) Another test of these pieces, is to look inside the vase, if the glaze stops at the neck - it’s a fake or reproduction. A real Roseville Pottery piece has the glaze all the way through. d.) Also see notes of #9.
9.) The words "Roseville U.S.A."., with the U.S.A. below the name. The right leg of the letter "R" flows to just before the "S" under U.S.A., and the "e" at the end of Roseville flows upward, almost looking like an "r". Actually looks like it reads "Roseviller instead of Roseville. The letters of this Roseville Potter mark should be impressed. 1937 - 1953. ( See the real mark to left).. a.) The word Roseville but without the U.S.A. has been copied from China. The majority of the China reproductions are copies of Roseville pieces made from 1935 to 1954. They have virtually the same shapes, patterns, colors, and mold marks as original Roseville pottery pieces. Copies during this period have raised letters "Roseville U.S.A.". b.) However a few fakes of earlier pieces (1910 to 1934) were also made. On these pieces, China marked the pieces the same as latter originals with the raised letters, marked "Roseville U.S.A." and then put a paper sticker with "Made in China" on the pieces (over the U.S.A.). Remove the sticker and how can you tell the old from the new? First try to determine the supposed date of your piece. Authentic middle period pieces have the single word "Roseville" impressed into the clay, the fakes are raised letters. The mark of the fakes in most cases is the opposite of the original (raised vs impressed). Second, watch for the height of the lettering, the raised fake marks have "U.S.A." as very faint or shallow, while "Roseville", shape code and size number are the same height. Originals have the ALL LETTERS, and numbers the same height. The raised fakes have skinny lettering, while the originals have bold lettering. Another test of the fakes and originals ,is the fakes have glaze on the inside around the top only. On the originals, the glaze covers the entire inside. Some of the reproduced pieces from 1910 to 1934 also have the glaze on the inside, but can be detected by the faint "U.S.A." mark. c.) Also see Roseville Pottery mark #8.
10.) The letter R, with the letters U.S.A. to it's right. The right leg of the letter "R" runs under U.S.A. 1937 - 1953. See fakes noted in Roseville Pottery mark #8 & 9.
11.) The letter R, with the letters U.S..A. below it. The right leg of the letter "R" goes through the letter "A" in U.S.A. 1937 - 1953. See fakes noted in Roseville Pottery mark #8 & 9.
Other Fake Roseville Pottery Marks
A.) Many footed bowls #197 have been reproduced and stamped "Made In Japan", sometimes this mark is sanded off - watch for color variation where the mark was.
