This 2007 auction catalog [https://books.google.com/books?id=ShOnykzju1QC] showing the De Wit Collection of Medieval Coins contains several coins that resemble the coin in your first picture. Check out item 1280 on page 402, which has a very similar cross surrounded by text "S I M O N". The text of the catalog is searchable in the online preview. I had some luck searching on "cross with two stars". Good luck.
