Another copy preserved at the Bibliothèque Nationale de France (public domain), link to the page of their website showing the photo of the coin: https://gallica.bnf.fr/ark:/12148/btv1b104421165.r=charlemagne%20denier?rk=321890;0 (more likely a die break than a globule on the obverse between the letters A and V).

Yet another copy preserved at the Münzkabinett der Staatlichen Museen of Berlin, link to the page of their website showing the photo of the coin: http://www.smb-digital.de/eMuseumPlus?service=ExternalInterface&module=collection&objectId=2439745&viewType=detailView.

Several copies sold by other auction houses. One coin seen, with perhaps a second globule on the obverse, under the first. In my opinion, it is a metal bubble like the ones we can see everywhere on the blank. Coin sold by MDC Monaco, link to the sale:https://www.acsearch.info/search.html?id=3495148.

The coins of Aix-La-Chapelle and Milan are very similar .. I considered that the coins with the mention MED are from Milan and that all those not having this group of letters are for the mint of Aix-La-Chapelle.
