An interesting find, indeed. (Sorry if this is a repost.) Here is an update: “Eleven coins have been found so far, scattered near Norwich in Iceni tribe territory. Their queen Boudica would later rebel against Roman rule.“ They were struck at Lugdunum, now Lyon, in France, between the last years of the 1st Century BC and the first years of the 1st Century AD - a generation before the Roman invasion in AD43. They are hardly worn and each has a tiny peck mark by the emperor Augustus' head, which Mr Marsden believes was done by Iceni craftsmen to check their quality.” https://www.bbc.com/news/uk-england-norfolk-61984020
The Denarius versions of the Augustus/Lugdunum coins are very abundant but I rarely see Aureus versions. This is a massive find.
Wow! The peck marks are interesting, in context. Seen on just one coin, one might say "what a shame", but seeing the three together tells a story.
