OPAL here is a new one for you. this the designer initial. this initial is less than 1 mm x 1 mm. it is and H on a Canadian dime. here i am using a camera bellows and a mitutoyo 20x microscope objective. to get the rest of the coins surface clear. i would have to use focus stacking. this is one single photo at about 20X magnification.

Thank you, but I just want to find out, what kind this coin is, and where it is coming from and it's age! Maybe there is an expert out there who can answer my question! My shots are just quick shots, and not very special! |

opal here is your coin. this is the leader it was created for.
Bactria: Demetrios I, Clay ! tetradrachm, c. 200-185 BCE
Weight: 4.13 gm., Diam: 25 mm., Die axis: 12 h
Diademed head of king facing right, wearing elephant scalp head-dress /
Nude Herakles standing facing, holding club and lion skin in left hand,
and crowning himself with his right hand,
Greek legend: BAΣIΛEΩΣ ΔHMHTPIOY
Demetrios I was the son of Euthydemos I and ruled (c. 200-185 BCE) after his father. He must have been a very capable man. Apparently he negotiated the peace between Euthydemos and the Seleucid king Antiochos III, and there is also evidence that he made inroads into conquering parts of India south of the Hindu Kush. His basic coin type, wearing an elephant scalp, symbolizes this as the elephant represented India to the Greeks.
opal there is no bronze coins listed. there is silver gold and copper. plus this baked clay coin. your coin maybe very very rare. hope this helps it was great fun. i owe some great coin photographier beer hehehe
he is the statement that goes with silver
Bactria: Demetrios I, Silver tetradrachm, c. 200-185 BCE
Weight: 15.79 gm., Diam: 33 mm., Die axis: 12 h

The size of the coin is 30mm, and its more exact weight is 25 grams! The coin is an heirloom from my brother who died unfortunately in 2009! He was an wellknown concert pianist who had concerts around the world. I think an good juwely shop should be able to find out whether it is gold or bronze metal! I guess it is time to find out!
Guys, thanks for all of your valuable help! |

Volume =π * 30mm * 6mm = 565.486678millimeters^3= 0.5654667centimeters^3
Gold weight by volume is19.282 g/cm3 calculated (24 karat gold grade)
0.5654667 * 19.28200 = 10.9033289g
Ref:

Either I've made a mistake or something else is amiss -- your coin weighs more than twice the weight of the same volume of gold. We know gold weighs more than bronze.
EDIT: Yep verified by http://www.traditionaloven.com/metal/gold-converter.html
Amount:
25 g - gram-s of gold
Equals:
1.3 cc - cm^3 - cubic centimeter-s
over twice the volume of your coin. So something is wrong because your coin weighs over two times the equivalent volume of gold. Are you sure it weighs that much and the dimensions are correct? |
