Are you interested in the coin, issued under a DISPUTED KING of France?   I think it is a very rare coin.

This Silver Douzain coin was issued under Charles de Bourbon, as a disputed King Charles X of France (1589-1590 AD).

Silver washed?   Blackened.   The Numista rarity index of Nimista-10066, is "74".   The index of "74" is too low, I think.

Heavily worn out for a long circulation, however the disputed king was in jail.

Charles de Bourbon, Cardinal de Bourbon, Archbishop of Rouen, was a French noble, prelate and disputed King of France as the Catholic Ligue candidate from 1589

-1590.  Born the third son of Charles of Bourbon, he was destined for a career in the church.  As a menber of the House of Bourbon-Vendome he was one of the

premier Prince du sang.   

 Henry III was King of France from 1574 until his assassination in 1589, as well as King of Poland and Grand Duke of Lithuania from 1573 to 1575.  As the fouth son of

King Henry II of France.  France was at the time plagued by the Wars of Religion, and Henry's authority was undermined by violent political factions funded by foreign

powers; the Catholic League (supported by Spain and the Pope), the Protestant Huguenots (supported by England and Dutch) and the Malcontents.

from the google systems.
