I said yes, but it depends on you you perceive as "value". And before anyone can give you that answer we need to see both sides of the coin plus weight and measurement. The holes in the coin will of course take some away from the value, againd depending on the reverse. BTW welcome @kimberlee becker
Your first question should be "What Emperor and what denomination is this?" Then..."Is it real?" Then we can discuss value. It is either a sestertius or an as of Hadrian. What is the size and weight, and do you have a reverse image? Can we also see an edge shot? I am reserving judgment as to the authenticity until I see pictures of the reverse and the edges, but if it does turn out to be authentic then obviously it is a damaged coin that was probably used as jewelry, and that will affect the value significantly. That green stuff could be BD. Is it powdery? If it is then you need to treat the coin immediately before you are left with nothing but a pile of dust.
Thank you for the welcome ...you guys are awesome! I don't have a small enough scale to accurately weigh this coin, but it is heavier than any other coin i have held. I did some research and did find it to be Hadrian. The size is approx. 1 1/4 inches and approx 1/8" thick.
I also have this coin which I believe to be that of Alexander the Great. Does anyone know if this is correct. This coin is small and What is BD?
Hadrian Æ Sestertius. HADRIANVS AVGVSTVS P P, laureate bust right, draped far shoulder / HILARITAS P R S-C, COS III in ex, Hilaritas standing facing holding palm & cornucopia, two small children flanking her. edit: Coin is from wildwinds.com. An excellent resource for info.
BD is a serious form of corrosion that will eat away at a coin fast. It is usually light green and it is powdery. It is not to be confused with green mineral deposits or green patina which will be hard and stable. If that green is powdery you may have a serious problem and need to treat that coin urgently. Check the green in those holes. It looks suspicious to me. If it is powdery, let us know for advise on how to treat.
Have to see pics for an id. BD = Bronze Disease. It's a type of corrosion that can spread to other coins
His coin has original patina from burrial and age, yours has been stripped of most of the patina which is why it is so bright. Same type of coin though.
The "child" in the right looks off, and the "S" and "C" are lower on the image you provided vs the OP's coin. I am not familiar with ancients, so the things I pointed out could be "acceptable variations".
Without the holes maybe around $80 to $100, with the holes I couldn't see someone wanting to pay over $50.
