Since all coins are a misture of metals and not a compound there is always that chance that to fast a cooling, to fast at adding the metals together, inapropriate temperature and numerous other situations could cause the mixtures to be less than homogenious. What I don't understand is if the Mint buys sheets of metals for the manufacturer of coinage, isn't anyone inpecting those sheets. If they manufacture the sheets of metals themselves, then such errors are understood. Anyone out there know if the Mint buys or makes the sheets of metals for coins.
Some of them look nicer than others, and most of them look just fine while they are red. Some of the ones that started out looking nice and red eventually start to tone really badly, and you end up with a technical grade of RB on a coin that looks like crap. Watch for red uncirculated copper that has some light pink striping in it...these are the ones that tone down really ugly.

I find it attractive !
Early S-mint cents, for example, are notorious for being struck with improperly mixed alloy and with a strong woodgrain effect.
Some collectors like it and think it's cool, but others think it's fugly.
Thanks for sharing that !!!!
I think I might have found my sub-type calling !
Anything "woodgrained"
