I've seen quite a few of these 1911's in such condition, and the restored example does from the images look like a great improvement. But for me there is just something about touching a coin that should never be touched, I dont know. At the price of a 1911 I would probably do it, but I would never restore an 1817 proof for example, I guess it depends on the state of the coin to begin with.
@Mike I don't have a huge opinion on the look of NGC slabs, it's the companies attitude to poor maintenance of pop reports, 100s of made up varieties, fake pedigrees, poor grading overall (imo), poor imaging, poor software, poor website. I mean, I cannot find any area they beat PCGS in, so why would i use them? The ONLY reason I think people use them in the UK is they feel it's easier, but I've graded 100s of coins with PCGS no issues.
