How can i tell of my "Heraclius and Heraclius Constantine. 610-641 AD. AV Solidus, Constantinople. dd NN hERACLIUS ET hERA CONST PP AVG, facing busts of Heraclius, with short beard and tufts of hair at ears, on left, and Heraclius Constantine, (bust much smaller), beardless on right, both wearing chlamys and simple crown with cross on circlet; cross between their heads / VICTORIA AVGU and officina letter, cross potent on three steps; I in right field; mintmark CONOB." Is real? And how much it's value is?
That's a nice looking coin TS. I would suggest you look on acsearch.info or Vcoins for similar coins and what they are or have sold for. In a quick search I found this one on acsearch.net that sold for $399 (220GBP): http://www.acsearch.info/record.html?id=667573. And here is another for sale on Vcoins for $564: http://www.vcoins.com/en/stores/for..._gold_solidus_graffiti_vf/434311/Default.aspx
