I think you are on the right track, though the flash could either be giving the 'look' of cameo, or washing it out. Given the images, I really can't guesstimate if they are cam's or not. Though, that '67 Lincoln, IMO, judging by the image provided, does not look cameo, to these eyes on this monitor, with that image. I'm just not seeing enough frost (I really don't see any) that could designate it cameo.
The Penny of mine might not be, but it was a close picture I had. There is frost but not much. As for the penny posted, I can not tell and as with mine, it doesnt look it but the eye and a camera see different things
Yeah I hear ya. Quarter and Half dollar in photo's look Cameo! Plus cellphone photo's are ok but not what you see in hand. Lights don't help or mess it up my hands shake at times to.
Cameo SMS cents are tough. If you want a proof memorial cent collection you'll need an SMS that looks proof.
True SMS cent are hard to find in Cameo or Deep Cameo appearance. But $1400.00 is a big price and twice what the grey sheet price is but it's still on eBay . Most likely will stay there .
