One coin sold by Fritz Rudolf Künker GmbH & Co. KG, link to the sale: https://www.acsearch.info/search.html?id=1705750.
The shape on the right shoulder appears to be a Latin cross. On the reverse, the wreath is wide and thin, the Chi-Rho is small.
Apart from a coin whose authenticity remains to be confirmed, all the Tremissi that I have seen show a bust with a double pearl necklace.
