kulraj, i think these coins are polished and finished for making unc condition. Wht do you think about you coins. Either cleaning or polishing for making true and fine. B'coz old coins are not having such shines and grace....tell the true pls.
its true that maximum number of times you find cleaned/polished coins but i assure you these are having 100% original mint luster. you can also have a look under East india company copper coins and see unc coin of east india company. George coins are rather easy to get in unc if you ask me. In fact I have unc coin of Bengal presidency also, minted around 1831.
