What happens to a "woody" that is acid etched?

Yeah, it is, in different areas. But within specific areas it's quite similar. Like in these 2 pics. In this one, the bottom half of the pic, all those grooves are pretty similar.

Same kinda thing in the upper half of this pic.

Your other 2 pics show more the kind of thing you normally see in a woodie, wild variation and irregularity.

But even down along the bottom edge of this pic, from the C and over and across the oak leaves, you see another area of consistency.

You don't normally see that kinda stuff in woodies.

 

Without going back and looking it for it I think he answered that already. He can correct me if I'm wrong, but I think he said he got the coin just as we see it now.

But moving on, this is what I was talking about Insider. I know they can come in all designs, but when you see an Indian woodie this is kinda what most of them look like. (I'm embedding the links for these pics.)









Now I don't know how any of those would turn out if we etched them with acid but I don't think they'd turn out quite like the one that started this thread did. The acid would almost certainly eat away the impurities or "dirty metal" first before attacking the copper. But I think you'd see great variation in the width and depth just like you see in the coins. And that's what has me puzzled about the other one.

Now back to another subject I said I'd get back too, the coin I posted a pic of. This one -




As I said before, when this coin was posted in the forum many believed or at least commented that it was a genuine woodie. Me, I was skeptical, I thought it was a "made" woodie. Faked in other words. So the member who owned the coin sent it to me to play with - and hopefully find out. And I did.

My contention was that if I was correct and dipped the coin that the stripes would disappear. If I was wrong they wouldn't, because the stripes just wouldn't be on the surface as they would if it was "made". Because on a genuine woodie the impurities would at least be down into the coin, if not go all the way through it and be visible on the other side as well, and in the same basic pattern and directions. And uh by the way, the other side of this coin was plain.




So anyway, I dipped the coin but I only dipped half of it. A 1 second dip in straight Tarn-X, I figured if you're gonna do it ya might as well go all the way.

Well to my surprise the Tarn-X didn't quite do it. It got rid of some of the stripes, just not all of them, as you can see on the left side.





I was kinda stumped because I figured straight Tarn-X would strong enough to remove any marker or whatever was used to make the lines, assuming they were "made". When it didn't, on the right side I decided to play some more. So I took a pencil eraser and I rubbed the area just above the date and just below the date. You can make out the traces of that in the pictures. And I left a little bit of them above so you could see they were still there in the dipped portion just like on the left side. And yup, the pencil eraser did the trick, the lines disappeared with nary a trace. So I was convinced, this was indeed a "made" woodie. Because with a real woodie that just wouldn't happen, couldn't happen.

Oh, one last thing, of course there weren't any grooves left behind from the impurities being eaten away by the acid either. Of course there wouldn't be because the lines were just on the surface. Had it been genuine, there almost certainly would have been grooves.

Now, why did I think it was fake to begin with, same reason as mentioned previously in this thread - the lines were too straight and regular - almost uniform. And besides that I had seen many, many similar coins over the years. And they were almost always sold as genuine woodies to somebody.

And to show what I'm talking about I went looking and dug up some pics of coins similar to the one I posted. Anyone who looks can find a lot of these.








And I believe they too are "made" woodies. So for those who don't know, when you see coins like these, be skeptical. And yeah sometimes they have corresponding lines on the opposite side - the people who make 'em get smarter as they make 'em.

Could I be wrong ? Yeah I 'spose. But I sure wasn't with the other one, and I'd bet if I did the same thing to coins that looked like these - they'd turn out the same way.

One last question. In another thread, and I can't recall who, somebody said that acetone would remove magic marker (a Sharpie) from a coin. Well I don't know, I never tried. But I know Tarn-X sure as heck didn't, and the Tarn-X even took some of the metal away - where the lines were too. So if it couldn't remove them, how could acetone ? Honest question.

 

Thanks. I figured whoever answered would do so with something along those lines.
