Maybe, in general, people could post images of less than 100kb as opposed to 9 mb. With 35kb (less than 1/200 the bytes) one can usually get an excellent coin photo. Most computers have programs that will reduce the "size" of images. (With an Mac the "Preview" program will do it.)
Thanks for your reply Doug Smith,i cleaned its surface,because on the surface so much black dirt. Why i suspect it,because i fill it`s a rude work ,and i don`t know how can formed the lines like following photo?like a mold.
IMHO the strongest case for the coin being genuine is the crystallization. A cast taken from a genuine coin that has crystallized must be extremely good to pick up the texture in a realistic way. The style strikes me as correctly archaic. I suspect the cleaning job reduced the value of the coin by 75% or so. Natural, dark toning with dirt filled recesses is strongly preferred by most collectors of archaic coins. Do note that crystallized coins can be a bit fragile. Dropping them can be a big mistake. Despite that, some of us find them quite desirable.
if according to yours opinion,in that shape,how much it can be sale?i just want to know what about it`s current value.
