+1 I have a Dachreiter type coming soon I hope. Not near as nice, but I will post it once I have taken my own images.
AV is standard shorthand for gold with ancients(from the latin avrvm or aurum). Similarly, AR is shorthand for silver(From argentvm/argentum) and AE for bronze(from aenevs or aeneus)
Looking in the dictionary, aeneus apparently does mean brass or copper, but this is the first I have heard it. Æ is generally held to be the abbreviation of aes (pronounced like 'ice'). Thus, Æs Grave, not Æneus Grave. Additionally, lead is abbreviated PB, from Latin plumbum.
Well I understand the elements with the Latin symbols. I have always seen gold written Au though, with that little non-Latin letter u.
It sure looks like that. But, Chris Rudd told me the Celtic people in Iron Age Briton struck their AV Staters in pale/rose colored gold. This man is the "expert" on Iron Age Celtic coinage from English tribes.
I'm a born sceptic, first off, so this be a little biased. But whether that's gold or not, something seems off when you show up two days ago and post dozens of gold (only gold) coins all over the forum. No follow ups, just "look at my coin" and move on to the next. Something just doesn't add up to me.
