Quote: Consulted the Encyclopedia Micro 'o' counterfeits and a strike-thru or two have been designated as VAM varieties.... now an alignment mark for locating the last two digits....... If the first two digits are floating around between near, normal, and far, how could spacing between the first two and the last two digits be achieved (using a constant alignment mark)? I see that 1878 dated coins are consistent in date placement (as are 1879 coins in relation to other 1879 coins). It is my opinion that all digits were removed from the master hub.... (If the first two digits remained, how are near, normal, and far dates possible)? How is the spacing between the digits kept so consistent? And the height does not suffer either as in previous issues of U.S. coins where this actually may have been the practice? I have seen such an effect on CBH, but I highly doubt that there were any date digits at all on the master hub used for 1880 and later... date digits can only be added to a die, not a hub, so the digits were either added to the master die (logical), or the working die (illogical due to labor intensive redundancy coupled with increased risk of error).

Why must you so easily blow holes in my carefully-constructed reality?  I gotta cogitate some on this.

Oh I know that you didn't come up with that jazz Dave..... I think that if there were two digits added to an existing two digits, there might be some noticeable differences (at the junction of these two sets of double digits) in relief, or spacing, or height, or curvature, or tilt..... not what I see when I look at the smooth transition across the four digits of a slanted date, or any other date for that matter.... (all four digits were added simultaneously the way I see it).

I would think that by the end of 1879, that an average die lifespan may have been arrived at, arming the mint with the information necessary to create the required numbers of master dies and working hubs to meet production quotas for each mint.... since this number surely exceeded production levels required by previous designs and denominations, (and despite the fact that New Orleans was ill equipped to handle such a pace), I would see no need to leave any of the digits off of an obverse master die.... I believe that all four date digits were pressed into the obverse master dies, and that by comparing date locations among a specific date might identify the master dies (as if just identifying the master hub isn't hard enough for the average person)..... How many master dies could be made from one master hub? Quite a few I might imagine..... with enough foresight, one master hub could create several master dies for for each year for several years.

OK, we'll take 1885-CC as a test case. 228,000 minted; given years of prior experience and what we know about what *can* be done on one die, it's not hard to believe that three or four total dies would do it.
Discounting "VAM-1," 3 major varieties are known (we'll temporarily pretend the coin which started this thread doesn't exist). None of the three appear to have the same date location, based on the position of the 1.
The OP coin is a bit of an anomaly in the date sense, as well - although the images aren't clear enough for decisive choices, the date location doesn't quite match my impression of VAM-2 or 3.
Idle question - would one think that a radial die crack might be a more immediately terminal condition than one running the circumference of the die? That's my impression.

Actually, I was referring to years rather than mints..... I doubt that certain dies were channeled to specific mints, so I considered that all dies are created equal, but that may not have been the case either..... 28 1/2 million coins struck in 1885. Yeah, but while a peripheral crack may be more likely to result in a Cud, a radial crack can be more noticeable (to me anyway).... as to which would be more terminal, I guess I would probably side with you.

None of the three appear to have the same date location, based on the position of the 1. Okay, I'll take that as a wrist-slapping for getting off track of the original thoughts..... I am, and have been, at least beating around the bush of the question of what VAM is it..... the question that would have to be answered first though might be: Is the light dash under the second 8 the feature that defines vam-2 despite cracks, and date variances (is this another one of those multi-die vams)?

Quote: Okay, I'll take that as a wrist-slapping for getting off track of the original thoughts No, quite the contrary. We've wandered off into the weeds, as you and I usually do, but it's all perfectly relevant to the coin in the OP. I believe it to be a previously-unknown (or unknown but unpublicized) obverse die due to the radial crack in the absence of the cirumferential cracks noted on other varieties. Our discussion of the date location and dash origin is relevant to this specific coin, because it'll help us figure out just what that coin might represent. As far as the dash goes, Leroy's reasoning meets Occam's Razor in my opinion. I am curious as to why they might choose the second 8 for a location - this is worth further thought - but its' status as a "locating mark" for a date punch makes sense. Would a mark closer to devices be less likely to basin out? I guess further clarification about the OP coin is up to mitchhailey, depending on whether or not he chooses to pull the trigger on it. Should he do so, we'd want closer inspection of the true date position, the shape and nature of the dash, and comparisons between any die cracks and the known locations of such on attributed varieties.

I wonder if all known dashes are common to one obv master hub?
Are there dashes under 7s, 9s, 0s, or 2s (or just the second 8)?
Would it not be reasonable to think that workers used a jig/screw press that actually locked onto the die as the date was pressed into it with a reference line to possibly the neck point?
I would not think that a properly radiused polishing plate would differentiate between device and field..... basining should not take the huge amounts of material that some folks may think.... except in early 1878, I doubt that basining was much of an issue (as the dies should have been the proper radius, or very nearly so, prior to basining).

I believe I have seen dashes under both of the first and the 8's not just the second one, but not for this year/MM , though the second seems to be the one most found to have the dash under it.

I would like if possible a close up picture or the first star neck point and the 1 date for die cracks, as well as the 4th and 5th star...if this is possible...

As near as I can tell, zee, the only dashes known are all over the tenth denticle from the neck point.

Quote: After 1879, the last two digits were removed from the Master Hub. Leroy mentions that, although the dash differs somewhat in its' relation to the 8 in various dates, it's always centered on the 10th denticle from the neck vee. After 1879 (but only through 1885)..... what a coincidence that during the years 1880-1885, these dashes are found in great abundance while these are the exact same years that digits remained on the master hub.

I'm still waiting for close up's?
