I can see how the punch worked on the reverse but not sure how any shape of punch could make the incuse area around the D but leave the D in place. Thoughts Rich Report this Post to the Staff

radatat Valued Member United States 492 Posts	Posted 07/01/2018 6:51 pm So if a gas mark, the same on the reverse? And not sure how the corrosive would do it and leave a fully round spot like on the reverse. Just interesting to me. Thanks gents. Report this Post to the Staff

Oh yeah David - never thought about it but those could be examples of zinc gas bubbles bursting under the copper plating! Good call. And ain't that some crap that zinc is actually poisonous to us!
