Another funderful find @galba68!!! Might I, a well known debaucher, recommend the conservative approach and that you not attempt to unbend that folded fella? Folds, like holes, dents, scrapes and dings add character. Like a pretty lady with gap teeth, kinda, makes you smile bigger.
Better first try to ID. It's silver and reads VOT- XXX. etc.. Whose Emperor on obverse? At your place, I'll ask a silver smith to fix it safely, even a little bit. Good Luck G68..
There is no hope for this siliqua..Its almost broken in half..I gave it to my friend as a gift, he will try to save the coin..The farmer's tractor nearly cut it off...
