I really cannot capture this correctly but this is missing most of the window panes where circled. Other panes are also partially missing across the full spectrum of all the windows. Wondering if this should classified as an over polished die, abraded die or struck through grease? This was a first pass on a whole solid date bank box and was so obvious I sorted all these out and ended up with 6 full rolls. Now I need to do a second pass for doubled dies of the window sills and columns. Yes, a very tedious job. But an interesting error (for me at least).
Is very difficult to see in this pic, but it could be any of the situations you mentioned. Can you see any die polishing lines? Would this area be a high pint on the reverse die? I don't know how your eyes will survive an entire box of 09 cents. Mine would extricate themselves from my head and hide under the couch. Good luck and I'm looking forward to seeing your other finds.
I don't think there is any issue. Looking at other 2009 Cents that area seems like no clear detail was intended for it. It's almost as if the Windows were shown through the columns to be shown kind of shadowy.
Actually, no as those without these missing panes are very clearly defined. The rest of the coin is also nicely struck. I see no die polishing marks anywhere on these so I'm rather stumped. Is it okay if I send a couple to you so you can see them in hand? I'd love to get a 2nd opinion. I've also heard here and elsewhere about the laser engraving process and maybe it's possible that the engraving was interrupted at some point and restarted and this was the result?
No die polishing that I can see and that's why I'm stumped. But as I mentioned to paddy, maybe it had something to do with the laser engraving of the die being interrupted and then restarted. Even grease does not ring true as all of the coins with missing panes are uniform. I would think that with this many all looking the same, there would be variations on the effect.
I don't know if this will help because of my lack of photo skills but possibly this might enlarge and you can focus in on the target are.
Absent any other evidence on the surface of the coin, the most likely scenario is that the planchet was improperly annealled (resulting in an overly hard planchet that was difficult to strike) and/or the dies were improperly spaced. Which mint produced your coin? Is it a circulating coin, or was it from a Mint Set?
Maybe someone had their window open when the drawing was made. After all, air conditioning did show up until the 1960's, not the 1860's.
