To start, I am not a beginner, I have dealt with tetartera for twenty years. They are small coins, successors the follis. Most Catalogs divide them into two different sizes, the full and the half. Now this denomination is common, money was abundant in the 12th century especially copper. Tetartera minted in Thessalonica were the low end of the coinage system but one of these coins could have bought you lunch. Not a great lunch, more like a bread and water lunch. The first tetarteron was created by Alexius I in the coin reform of 1092. The coin was minted in large qualities until the fall of Constantinople to the Crusaders in 1203, they were invited as guests and well the chose not to leave. The coin was minted after 1203 but are much rarer to be found. This group is in aVF condition, a good mix of full and half tetartera. We have 49 coins in the lot.
