From Menorca/Minorca you seemingly can't travel to the city of Rome in a straight line without intervening landfalls, but you can hit northern Italy. I believe all of that was "Rome" by 63 BC. Next player may proceed from mainland Italy or anywhere that was under Roman rule at the time the coin below was struck. Ancient Roman Republic: silver denarius of moneyer L. Furius Brocchus, ca. 63 BC
From Sardinia back across to Italy, down in the "boot" at the lower part of its peninsula, we find Calabria. (And I find an excuse to post one of my favorite 2017 purchases. Again.) Next player may again proceed from anywhere in Italy, but preferably in a straight line from Calabria if you're making a water crossing. Ancient Greece (Spartans in Taras, Calabria, Italy): silver drachm, Athena and owl, ca. 302-281 BC (NGC XF; Strike 5/5, Surface 5/5)
Headed north of Italy to Austria. I hate to play such a modern coin after that beautiful Ancient coin of @lordmarcovan , but it's all I got.
Modern coins deserve respect, too. It's all good. Hmm... let's see ... Bohemia is largely the modern Czech Republic, I believe. And the German state of Bavaria contains the city of Nuremberg (Nürnberg). And this gives me an èxcuse to post my latest purchase (so recent it is not yet in hand): this Nürnberg 1/8 thaler klippe commemorating the end of the Thirty Years War. @chrisild shared the history of these in a very helpful post. So play from Nürnberg, Bavaria, or Modern Germany. I have long been a fan of the type. Love that little kid on the stick horse. Back some years ago, I had one of these on my old Holey Coin Vest. It was one of my favorite "holey" coins.
From Holland to Gelderland keeps us still within the modern Netherlands. Netherlands (Gelderland): "St. John" type goldgulden (florin) of Arnold van Egmond, ca. 1423-1472
Brabant. Next person may still play from Belgium. Belgium (Brabant): gold florin (Carolus d’or) of Holy Roman Emperor Charles V, ca. 1521-1545
Sorry for any repetition. With a such a small collection, I often repeat myself in these picture posts. Switzerland (Zurich): silver "city view" 1/2-thaler (1 gulden/36 schillings), 1739 (PCGS AU58; population 1- the only example certified by PCGS as of 11/04/2017)
I always liked those bimetallic Italian 500-lire coins. They rank high on my list of attractive circulating moderns. Let's head over to Greece while we're still in the Mediterranean. Ancient Greece (Corinth): silver stater featuring Pegasus and Athena, ca. 345-307 BC (NGC AU; Strike 5/5, Surface 3/5)
From Greece to Albania: The Albanian coinage of this time frame was designed in Italy, under the influence of a King who loved the motifs from ancient Greece and Rome. It shows.
From Montenegro to what is now Croatia. Medieval Croatia (Ragusa): silver grosso portraying St. Blasius and Christ, ca. 1372-1438 (PCGS XF40, population 1: the only example graded by PCGS as of 12/20/17) This one (affectionately dubbed "The Hippie Coin") has gone to live with @dadams now, but is welcome back here any time.
