I pay cash for classical sheet music in good condition. Markings in pencil, pages folded or dog eared for page turns, name labels, and light wear or stains are acceptable. Older, nicer editions, especially European editions, are preferred. I'll buy small lots to large collections. I resell individual pieces and maintain a large inventory, sometimes holding for years until the right buyer (usually a music professional) comes along. I also buy some large format popular music from the late 19th and early 20th centuries, like new or new contemporary sheet music of all types (folios, methods, collections, etc.), and pristine tablature transcriptions of metal albums. I am a small online reseller. Happy to travel for several boxes or more.
