I suspect that Pete has just bought that 1858LRSD Cliff, no doubt he will be able to confirm..... think he almost made the post at same time in the 'coin acquisition of the week' thread.... so I wouldn't spend a lot of time looking for it on ebay or elsewhere.
Maybe but Collectors Coins Great Britain says not, and neither does https://en.numista.com/catalogue/pieces4412.html
Some of them have mintages listed too which isn't conclusive but it'd suggest at least some of the years were made for circulation.
I did find this https://scholarslab.lib.virginia.edu/blog/automate-downloading-pdf-files/ and after a lot of messing about created something that would bring up the site and page thru the pdf. This whole process is a dogs dinner. The Ui.vision documentation is laughable.
