A little preface: For the past ten or so years, I've squirreled away a huge pile of world silver (about 2,000 pieces, mostly better/older/cooler stuff.) I've finally come to grips with letting a good portion of it go, so I'm going through and weeding out the ones I care more about than others. I was going through my British shillings and accidentally discovered I have an 1859/8 - but Krause/NGC/eBay/Google are giving me nothing but blank stares and empty slots. Does anyone know if this is a desirable or relatively common overdate variety? I'll get some pictures up later; coin appears to be in around Fine condition with a probable cleaning. Thanks!
Nothing in my Books, Spink, Coin Year Book or Tony Clayton's site. http://www.coins-of-the-uk.co.uk/values/onesh.html
Apparently PCGS has graded two, an MS64 and an AG03, so the variety does exist. No mention of values yet, though.
I found one auctioned in 2017 for around $200... it also gives a couple callouts of the Die/Variety, but I'm not familiar with those. Thought it could help! http://www.londoncoins.co.uk/?page=Pastresults&auc=156&searchlot=3448&searchtype=2
No huge interest, just a little I found one that PCGS blew the grade on but got an IMO correct "58" from NGC. Really not exciting, but not junk if in higher grade obviously.
