How To Tell Red, Brown , Brown Red Coins. Apart ?for Grading A Coin

This obviously leaves a large swath for an RB classified coin. For most grading purposes these classifications are use by grading companies on higher grades as opposed to a common circulated coin. To put it more in perspective, an LMC say an 1968S in XF40, would seldom garner the RD tag, circulation has taken its toll, skin oils cause the oxidation process to accelerate at a much faster pace. An uncirculated, never out of mint cellophane say a 1964D may also have naturally began its natural oxidation process and lost some bright color, it is now considered a RB because 5% or more of its fresh off the floor color has been lost.

Now remember too, a color classification isn't a grade per se, but a stamp of "eye appeal" making that coin more desirable to some.

Thank you both for input and on the links to look at.The main ones get me are the 60 s with the Amber gold like finish. As well as the red browns of the newer coins These links help make that less confusing

Thank you for all your help and yeah I like the PCGS pics for trying figure something out as well as yours co-op you have alot good photos to help people like me.
