Craig Helm is volunteering his time to help us out with this. Craig is a certified appraiser, but he simply can’t know everything about everything. He told me he knows the most about: Native American and pre-Columbian artifacts, antique pictures, western memorabilia, and Asian artifacts. (Please note that no guns are allowed on the Cuyamaca College campus.) He’s not prepared to answer your questions about gems and minerals, or stamps.
