Half of the obverse on this 1993 LMC has a goldish yellow color. It doesn't appear anyone attempted to polish it I was just wondering what this could be from. Also, it looks like there is reverse grease effects? Thank you

Copper coins quickly take on many different colors as they circulate in different environments. Looks like grease effects in States.

Correct about obverse..envrn. toning...Reverse has 2 issues ..1) over-polished die to "floating" roof area..2) Area of "States of" not a grease filled die issue,but a lack of metal mass to fill both devices of the obverse and reverse..this issue was talked about in a recent post..
