Is it walnut, maple, oak or an exotic? The condition is important as is the design. Being designed or manufactured by a renowned individual or company known for high quality always adds value. A good bit of 'burled' furnishings from that period were inlay or veneer rather than solid wood. Try to find any markings on the pieces which may indicate the manufacture and then do more research. If you choose an appraiser make sure it is one who is reputable and has no connections with a sale or purchase. Actually, try to have three qualified individuals to look at he pieces. If there are inconsistencies in the wood, fittings or fixtures..do not attempt to 'repair' them as that can often lead to a diminished price. Often, an original in not-so-good condition is better than one that an amateur tried to fix/repair.
wow this sounds fantastic....
i think you need to consult with a proper antique dealer....actually i would use at least 2..
if you let the first dealer think they are the only dealer then the estimate may be low. if the are aware upfront there are several coming to have a look then you will get a more honest figure.you have not stated how many pieces there are or the colour or condition. all these things count. also try googleing antique bed sets.
