I played here in Assassin’s Creed: Bloodlines and, having nothing to do, I thought to find all the Templar coins in the locations. Since I did not find any special information on this matter, I decided to find them myself.
In total, each location has 6 coins – 1 gold and 5 silver. Silver coins are usually found by themselves, while gold coins are hidden in more inaccessible places: on the highest towers or in some nooks. For coins, you can purchase improvements for the hero, as well as get “achievements”.
The archive contains screenshots with the marked location of these same coins. The game is already old and hardly anyone plays it, but maybe someone will come in handy.
