I thought this would make an interesting collage to share, this is coinage of the Alexius Reform of Eastern Roman coinage in 1092. It remained consistent through the 12th century and for part of the 13th century. The highest to the lowest denomination of the time. All are coins from John II Comnenus. All of the coins are in pecking order. This is the current thought, 1. Hyperpyron SBCV-1938 2. Aspron Electrum Trachy SBCV-1941 3 of these are worth 1 Hyperpyron 3. Billion Aspron Trachy SBCV-1944 16 of these for one Aspron Electrum Trachy (48 to Hyperpyron) 4. Tetarteron Billion SBCV-1945 6 of these for one Billion Aspron Trachy(288 to Hyperpyron) 5. Tetarteron SBCV-1953 3 of these for one Metropolitan tetarteron (864 to Hyperpron) 6. Half tetarteron SBCV-1955 2 of these to make one tetarteron (1728 to Hyperpyron) I do not totally agree on the lower end , too much issue with weights but this was the most logical order that was presented by Michael Hendy in Dumberton Oakes Catalog IV 1999 AD. Overall it is interesting to see them together.
Very interesting! I only have three billon aspron trachies. Alexios I Manuel I Latin issue (calling this one billon is kind of a stretch)
Amazing representation! If I understand it correctly, a Aspron Electrum Trachy has the same value as a Hyperpyron, why is this? My Billion Aspron Trachy: Manuel I Komnenos Billon Aspron Trachy (1143 A.D. – 1180 A.D.) Obverse: IC - XC. Christ Pantokrator seated facing on throne. Reverse: Manuel standing facing, holding labarum and globus cruciger, and being crowned by the Virgin standing to right. 3.30g; 30mm
No, it took three Aspron trachea to make one hyperpyron. I have now highlighted the amounts, I left out a comma that made it confusing. Sorry
Yes I just noticed, I misread it It would be interesting to find out if the amount of gold content in 3 electrum trachea is equal to the gold content in 1 hyperpyron.
That was my mistake, Ive corrected it. The Electrum aspron trachea were not trusted , critics of the new currency did not like any of the mixed metal coins because you could not clearly test them for metal content.
