I'm not a woody expert but it does appear to be one based on your pic but let's see what other's think. Dave
Improper alloy mix. Looks like a classic Woodrow. Is it streaked on the reverse too? I can't tell from the photo, and I assume it would be on both sides if it is all the way through the alloy.
AH OK. I wasn't sure. I figure the alloy mix has to go through the whole sheet of planchets, and why wouldn't it be on the reverse, and not on the obverse? Most of the ones I recall are always heads.
A "woody" doesn't necessarily have to show on both sides. Although both sides is fairly common on earlier examples, it is actually (hopefully I'm remembering this correctly) somewhat of a rarity on later ones.
I'm sorry, I did not mean to imply that there are not woodies with both sides presenting, just that I have not found any to date. They are out there, just have not passed my way yet.
That surprises me, but there isn't a doubt in my mind you'll find one. A few years ago I remember finding a late 70's cent in change that displayed this rather strongly on both sides, but isn't a common thing. Like I said before, I believe it's more common on earlier dates. Good luck!
