<p>[QUOTE=&quot;Herberto, post: 2297255, member: 74222&quot;]These copper tetarteron are not entirely typical Byzantine coinage as the contemporary scyphate coins are, and in which origin can be traced back to Anastasius’ monetary reform. Tetarteron can be traced back to Fatimid coinage(or somehow).</p><p><br /></p><p>If I remember right the Tetarteron was once gold and it came as result as the Macedonian Dynasty’s expansion over Muslim’s lands, where a lighter gold coin than Solidus circulated there. At a time both the lighter Tetarteron gold coin and Solidus coin circulated at the same time within Byzantine hemisphere.</p><p><br /></p><p>Solidus became Histamenon, a tinier fabric gold coin in order to easier distinguish it from Tetarteron gold which was a thick small gold coin. Later that Tetarteron gold became copper for whatever reason I don’t remember why.</p><p><br /></p><p>The first 3 are Tetarteron copper, and the last 2 the contemporary scyphate coins.&nbsp; </p><p><br /></p><p><br /></p><p>Alexius Komnenus,&nbsp; sear 1932, 1,6cm, Thessaloniki.</p><p>[ATTACH=full]461291[/ATTACH] </p><p><br /></p><p><br /></p><p>John II Komnenus and Yeezus, sear 1954, 1,3cm, Thessaloniki.</p><p>[ATTACH=full]461292[/ATTACH] </p><p><br /></p><p><br /></p><p>Manuel Komnenus and Mary, sear 1968, 2 cm, Constantinople.</p><p><br /></p><p>[ATTACH=full]461295[/ATTACH] </p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p>And the scyphate coins, cup coins, which are larger than the above:</p><p><br /></p><p>John II, sear 1944, Constantinople.
