January 20, 2012 A Stoner COA January 20, 2012/ Steve On January 10, I wrote about junk COA whack-a-mole. When one phony-baloney COA gets banned from eBay, another cheeseball COA will soon appear. Exhibit A: Certificates of Authenticity from Michael A. Stoner, Esq. Does anyone know this guy? Who goes to a lawyer to authenticate or buy an autograph? What's next, Marcus Welby, MD COAs?
