Thank you for contacting the Rakow Library. Your lamp is probably by the MacBeth-Evans Glass Company which was formed in 1899 with the merger of two Pennsylvania glass producers, the Thomas Evans Co. of Pittsburgh and the George A. MacBeth Co. of Charleroi.  Both companies were major manufacturers of glass lamp chimneys.

As a non-profit, cultural institution, The Museum cannot offer appraisal services. If you wish to determine the value of your glass piece, you may want to consult a reliable local antique dealer, or send a photograph of the object to a reputable auction house (see ArtNet’s directory of auction houses worldwide, http://www.artnet.com/auctionhousedirectory/index.aspx).

You can also find appraisers through several professional organizations: The American Society of Appraisers (phone) 1-800-ASA-VALU (online) http://www.appraisers.org; The Appraisers Association of America (phone) 212-889-5404 (online) http://www.appraisersassoc.org; and The International Society of Appraisers (phone) 312-224-2567 (online) http://www.isa-appraisers.org. 

Your local library may have a subscription to Maloney’s Antiques and Collectibles Resource Directory, which provides listings of appraisers by type of collectible. Plus I suspect that you have already looked for internet sources. That is always helpful to see if there are similar items listed for sale.

Let us know if you have further questions.

Best regards,
