Many thanks for your kind replies. My initial thoughts on this was it was too worn to fetch great value. Also, in the UK at least, just being Roman does to immediately make it super-special. Now, given this additional information from these postings I think I may set it off on eBay with a minimal starting bid and let the market determine fair value.
When I do list it, would it be appropriate to put a link to it in this forum on somewhere else on this board?
Thank you again everybody, great to have found this source of opinions and information!
