  1. [I apologize if I didn't see this already posted as I did try to search.] I'm not sure how many of you knew Michael Luck but I happened to be friends with him, although I never met him in person, for a number of years. Unfortunately, we fell out of contact for the past few years and I only came across his obituary by doing a search for him in Rochester news (since he belonged to the RNA). He was a very interesting character who was extremely passionate about numismatics and had a tremendous amount of knowledge. I'm curious to know if anyone here was in contact with him before he passed away and knows what he was doing over the past few years and what he died of. I do know that he had pretty severe diabetes and his kidneys were at low levels of efficiency even a few years ago, but I don't know anything beyond that. Also, I did notice that this was posted back in August on the PCGS site.
  2. All coins have problem-free, original surfaces unless otherwise noted. Please feel free to ask me any questions. USPS Priority Shipping is a flat $7 for any order. 1855 3¢ - VF [$125] [coin exhibits a somewhat weak strike] 1875 3CN (#1) - VF [$32] 1875 3CN (#2) - VF [$32] 1882 3CN - XF [$225]
  3. Joe, I'm glad all is well with you and your family. Also, thank you for documenting what you did. It's quite fascinating to see what happens in a real-life situation to such safes. I'm curious to know if you knew anyone with safes that were stored in a basement and if those fared any better or are there really no basements in Paradise?
  4. Not as much as you think anymore. Yes, there's a ways to go, but the object recognition technology is getting exponentially better each year. Recognizing raised devices on a coin...I think that is already in today's realm of computational possibility.
  5. I would assume that the experts could be fooled if the luster was applied by using AI applied algorithms which exactly mimic what would be seen on a freshly struck coin. The techniques for doing this would be complex and take a lot of trial and error, but I would think it's in the realm of possibility.
  6. I have to wonder if there isn't a high-tech alternative. I would think that maybe it's possible with a combination of lasers and decent AI. There might be a materials expert here to correct me on this, but I believe those flow lines are nothing but a bunch of radially spread micro crevasses. For the record, I'm not advocating that this ever actually be done, this is more of an academic exercise. However, it might be worth thinking about in case the technology does become more advanced and inexpensive. It would be pretty amusing to see a fully lustrous coin in Good condition, huh?
  7. I don't think I've seen any serious discourse on this topic and maybe I missed it somewhere, but I'm very curious to know if this is remotely feasible. Look, it's just physics! LOL Of course, I'm not talking about whizzing here...which is simply just destroying a coins surface to get a sort-of lustrous effect. Assume the coin in question is a super choice AU seated quarter that has been over-dipped and "stripped" of its luster. I realize that luster is essentially light reflecting off of the coins microscopic, radial lines produced when the dies strike the metal (and I apologize if my description is not quite accurate). But, I could imagine that someone has invented or could invent a technique where you could subject a coin to some process where the fields are exposed to some element or stress or whatever in a radial fashion (while not disturbing the devices) to reproduce the missing "luster" where it could be virtually undetectable to the professional numismatist. And, if such a technique does not currently exist, I got to imagine it's a matter of time before it becomes in the realm of possibility.
