I am not commenting on the authenticity as I really cannot tell from the images. However, I do not believe it is a Siligua but rather a Miliarense: Thessalonica RIC VIII 91 Constans, AR light Miliarense, 24mm, 340-350 mm, Thessalonica. FL IVL CONSTANS P F AVG, rosette-diademed, draped, cuirassed bust right / TRIVMFATOR GENTIVM BARBARARVM, Constans in military dress, standing left, holding a Vexillum with o on banner, and resting hand on shield at his side. Mintmark TES. RIC 91; RSC 115. Take a look at the reference on wildwinds: http://wildwinds.com/coins/ric/constans/_thessalonica_RIC_VIII_091.jpg
As to the price, take a look on acsearch.info: http://www.acsearch.info/search.htm...n=1&de=1&fr=1&it=1&es=1&ol=1&sort=&c=&a=&l=#0
This is a Medallion and my question is. Because its bent and it is damaged, can someone estimate its price?
The prices realized for Madallions are also listed on the acsearch.info page I showed earlier. Condition will have to be taken into consideration, but the value will have to be estimated by someone other than me.
If authentic, that would still be a difficult coin to price. You may want to take it to a reputable dealer to take a look at it - if you live in Indiana, Harlan Berk in Chicago isn't too far.
