Jamie Colwell is an antiques and collectibles writer and editor whose guides have been referenced by Indiana University of Pennsylvania and the Dutch national magazines Libelle and Margriet, among others. At Know Old Stuff, where she is lead writer and editor, she has written more than 110 guides since 2025, on everything from Depression-era glass and vintage Pyrex to antique cameos, Hummel figurines and old Singer sewing machines.
Her current focus is the everyday pieces that turn up in family cupboards, attics and estate sales, and what they really sell for today. Every guide starts from completed sales, not asking prices, and draws on maker’s marks, backstamps, old catalogues and patent records.
Jamie’s guides are at their best on the pieces that look ordinary but aren’t: the plain jar with the right mold mark, or the teacup with the one backstamp collectors look for.
