NGC Cert # 4497067-001 NGC Description 1904 USA-PHIL PESO NGC Grade PF 62 Because of the 2 spots on that coin - I would almost consider conservation. There is something on the coin causing the spots. Cant hurt to send to NGC for an appraisal Regards Your Friend Mike - jgrinz
Hi Mike, I've had it for several years and it seems stable. There is a small milkspot-like area and then an untoned area around it. I'm not certain conservation would help and I'd be concerned that NGC would dip the entire coin and thus harm it more than help (and charge for the service).
