  1. Personal preference really, I just wanted the highest number available to use a single digit, so I chose 1111 as I wanted to limit the quantity and use a 4 digit number.
  2. Thank you for your reply. From the medallions I have checked so far, there are probably 5-8% that I subjectively grade as excellent. I am trying to get an idea of if I am looking too much for perfection, and if what I am classing as unacceptable is actually normal. In the video I was trying to show the fine lines that run horizontally across the shield. The video was short because I could only upload 5MB and I wanted to keep the quality high as I thought it would preserve the lines better. With a bit of trial and error I should be able to find a good compromise between video length and quality. I minted 1111.
  3. Dear Silver Forum Community, I am interested in your feedback on flaws due to the minting process. I designed a one ounce reverse proof silver round which I had manufactured by a mint in Australia. I produced it with the intention of it being a premium product, limited edition, numbered COA and individual laser engraved number. I have been individually inspecting each piece to make sure I am satisfied with the quality. I have found a few so far with an impression of a hair or fiber, but the main issue is what I believe to be striation lines. Some are more obvious than others but the luster is dulled to varying degrees where they are present. Some need to be viewed from an acute angle to notice, whereas others are immediately visible when viewing the round normally. I have attached a short clip showing the lines on one round that can be seen clearly. I rejected this one. I have just been looking some coins from my collection that have been produced by the Perth mint etc. and the first thing I noticed was that the polished areas often had the lowest relief. This is of interest because I had noticed on some of my pieces that the striation lines disappeared in the lower relief areas of the design. This leads me to wonder if the greater movement of physical material in the lower relief areas in the stamping process can remove certain types of striation lines that appear on a blank. Anyway, after looking at these other coins from major mints I think my rounds are quite good generally, and maybe I am being too harsh, but so far I have rejected about a third of the rounds, due to any obvious flaw including a dulled area of luster due to fine lines on either side of the round. Before I had a look at the other coins in my collection I was discouraged by the number I was rejecting, and I was considering getting them all remade by another mint. However, now I am thinking about just getting the mint to remake the rejected ones. Personally, I think it comes down to whether or not I would be happy to have this round in my collection after buying it. And since I really like how the design turned out, and if there is no obvious flaw, the simple answer is yes. The limited edition and individual numbering are just bonuses. I would like to know the perspective of the community. lines.mp4
