More fake and misleading items are appearing for sale.  New collectors should obtain guidebooks that picture both authentic and reproduction items.  Note that RS Prussia factories in Suhl, Germany and Tillowitz (now in Poland) did not manufacture "oyster plates" and "wash stand pitchers".  A helpful reference is the International Association of R. S. Prussia Collectors' site - rsprussia.com, then click "Fakes and Reproductions".  Often, authentic R. S. Prussia feels light and delicate, whereas fake items are heavy and feel more like pottery than fine porcelain.

There are several different authentic R. S. Prussia marks (including related collectible items), and again the guidebooks can help in recognizing and authenticating them.  Most real marks are under the glaze.  In most cases, authentic wreath-and-star marks are subdued in color, whereas the counterfeit marks are vivid and look amateurish.  Real R. S. Prussia marks show a period following the word "Prussia" (in most cases - sometimes aging causes areas of the marks to wear).  Counterfeit marks that often appear are the wreath-and star that encompass the letters "R" and "S", but without wording below; and the wreath-and-star with "Suhl" printed below the wreath.  Of course, there are authentic versions of these representations.  The R. S. Prussia web site lists currently available books that provide details on fakes and reproductions.

R.S. Prussia values range from the floral pieces, with higher values for scenes, portraits, animals decors.  A 2006 auction saw a cobalt scenic pitcher sell for $10,000.  R.S. has great potential for increasing in value, and many, if not most, pieces have a timeless appeal due of their artistic shapes, beautiful coloring and striking designs.
