Namachieli Pillar of the Community United States 2120 Posts	Posted 10/12/2011 2:42 pm I'm still learning a lot about this series, but for some reason the alarm in my head just went off. Key spots 12 oclock OBV, looks like missing metal. Is it just crud? The Z for Zactecas seems oddly shaped The wear on the edges seems inconsistent with the rest of the coin Assuming this is real (pun intended) I would wager a guess in the F/VF range. I don't have a price guide readily available at the moment to look up price. Report this Post to the Staff
CowboyB Valued Member United States 110 Posts	Posted 10/12/2011 3:53 pm I am trying to figure out what that is between 10-11 o'clock on the OBV picture. It looks almost like solder but I don't have a microscope yet to really take a look. Could the other marks be Die Stamps? I don't know much about this series either but trying to learn. I think it is Real (pun inteneded) but not 100% sure. Thanks! Report this Post to the Staff
brokencompass Valued Member United States 451 Posts	Posted 10/12/2011 3:58 pm I felt the same way too, something felt a little different about the coin. Here are a few thoughts that I had 1) The coin might have been cleaned, there are plenty of cleaning pattern scratches on the reverse 2) The loss of detail on the edges could be a weak strike or a die issue but it is also consistent with cast coins that have more detail in the middle and lose detail around the edges 3) What kind of an edge does the coin have? I would grade this VF 30. Edited by brokencompass 10/12/2011 3:59 pm Report this Post to the Staff
swamperbob Pillar of the Community United States 5362 Posts	Posted 10/14/2011 3:50 pm First off - the coin is real. The shape of the Z is correct and I have no suspicions about the authenticity whatsoever. The strike is as suggested UNEVEN. It must be remembered with this series that it was produced on an open sided screw press and the perimeter of the coin is dependent on the successful upsetting of the blank BEFORE the strike. The edge design application was also the UPSETTING process which turned the coin blank (a flat disc) into a TRUE planchet. A planchet is NOT flat. To get a good edge to strike up it is critical for the planchet to be THICKER at the edge. The pressure of the edge application causes the blank to thicken at the edge. All properly struck coins require a thicker edge because the pressure DROPS at the perimeter and the thicker edge makes contact there happen FIRST. A flat planchet would always have hopelessly weak edges. Now in actual practice, IF the blanking mill dies have worn out of round and the blanks are no longer EXACTLY round the edger can grab the blank differently (at different pressure) AND create a thicker and thinner upset. The difference is actually a fraction of a millimeter in diameter but there can be down stream effects like you see here. It is typical of collarless strikes. That is one reason why a FULL strike is important in grading considerations. Post strike damage is also a consideration when grading this coin. The chop marks while considered interesting by some - is often classified as damage and grading companies do not often grade these. But in addition there has been some corrosion here which was partially removed. The "problem area" noted at 11 o'clock is corrosion that resisted removal when the coin was cleaned. The black areas between the rays may be pits or lumps of the original corrosion as well. I would net grade the coin at F-VF. Report this Post to the Staff
dosmundos Valued Member Germany 194 Posts	Posted 10/14/2011 6:52 pm Well, not much to add to Swamperbob's observation. A regular 1888ZsFZ 8 Reales, which is a common coin, with a weak strike at the rims and some small chopmarks that are considered detrimental to the coin's value. Grade is VF (full LIBERTAD, and the weaknesses in the design are due to strike and not wear). Value, I guess, is more or less the silver content... Report this Post to the Staff
