Photo of a coin sold the 21/06/2020 by Auctiones GmbH, eAuction #68, lot 137, link to the sale: https://www.acsearch.info/search.html?id=7105645, link to their website: https://www.auctiones.ch/.
The bust seems to be cuirassed with drapery on the left shoulder, this variant is confirmed by a coin sold by Paul-Francis Jacquier (awaiting photo rights to replace the illustrated copy by this one), link to the sale: https://www.acsearch.info/search.html?id=3258842.
Auctiones GmbH gives a diameter of 18-19 mm, I chose the larger diameter because the coin has an oval shape and part of the beading is off the blank.
