[QUOTE="lordmarcovan, post: 7922893, member: 10461"]That’s a good test for depth of mirrors, and I know people use a similar test, like trying to read reflected newsprint when checking for prooflike (PL) and deep mirror prooflike (DMPL) status on Morgan dollars. But the depth of the mirrors alone is not [URL='https://www.greysheet.com/news/story/grading-cameo-contrast-on-u-s-proof-coins']what makes a Cameo or Deep Cameo[/URL] proof. It’s the [I][B]contrast[/B][/I] between the mirrors in the fields and the frost on the devices. You have [B]Brilliant[/B] proofs, like the coin above, which can have lovely deep mirrors, but they have no contrast between the fields and the devices. The next step up is a [B]Cameo[/B] proof (CAM) which (like a [URL='https://en.m.wikipedia.org/wiki/Cameo_(carving)']jewelry cameo[/URL], from which the term derives) has contrasting elements: mirrored fields but frosty, matte devices. Above that is the [B]Deep Cameo[/B] proof (DCAM), where the contrast is especially striking. These will have a true “black-and-white” appearance, with “caked on” frost on the devices, very deep mirrors, and a starkly visible contrast between the two. Modern proofs are usually DCAM by default, due to how the dies are prepared nowadays. But the reason CAM and DCAM are a big deal on pre-1971 proof coins, and Franklin halves in particular, is because [I]Brilliant[/I] proofs were the norm back then, and only the earliest strikes off the freshly prepared dies came out CAM or DCAM, if any at all.[/QUOTE]
