If you are lucky enough to own a Herend Rothschild Bird tureen with under plate it is probably time to cash it in. This is another estate piece that I recently appraised at $1,000! There is one currently for sale without the under plate on ebay for $1,100, Replacements sells this piece for $1,399. Pricing differences will always occur in the antiques and collectibles market. You will rarely find consistent pricing on items since each individual seller can ask whatever they want for the items that they are selling.
