Cam, DCAM, And Ucam Which Is The Highest Rating On A Coin?

Same here.

I think it's a trademark thing.

Depends on the coin.

Cam, D Cam and U Cam are terms that relate to the quality of the strike of the coin and are unrelated to the condition of the coin, or the relative rarity of the coin, with the afore mentioned striking qualities.

The level of rating of CAM, DCAM and UCAM do not relate to condition or rarity, but to striking quality. The only exception that I can think of are PL and DMPL Morgans, struck from fresh business strike dies in high MS grades, where the devices exhibit a cameo effect. In this case condition and quality of strike do play a vital role in their valuation.

Having said all of the above, I have seen some very poorly minted UCAM silver rounds.

Yes.

Correct.

Also, NGC uses PF while PCGS uses PR.

A PCGS PR69DCAM would be an NGC PF 69 ULTRA CAMEO

I have been learning so much stuff here that my brain is getting full


So could someone please tell me what this thing is used for?

I don't think it's a trademark deal as much as it's one company trying to differentiate themselves from everyone else because Icg also uses the dcam designation ! NGC just wants to cause confusion lol good question though I had the same one long ago

to the Community, Jolynn1002!
