Thanks for your question! Baldwin is a well known company with a reputation for quality. Their Hamilton line was one of a couple different names they used on uprights. The finish and size of this piano will allow it to gain some value. Considering depreciation from age and the used piano market, you could expect to sell for approximately $2,800-$3,300 in a private sale. Best wishes!
