Topic: China yuan shih kai silver dollar coin with unique die clash error?Help plz

[chinese_item]

Hi.I have a piece of China yuan shih kai silver dollar error coin in used condition.Unfortunely,I still not sure if it is a die clash error coin or not because the HUGE ROUND AND STRAIGHT LINES RAISED OVER THE ORIGINAL DIE on reverse side and there is an unusual shade just right below the chinese word "yuan" and the shade is not RAISED on the surface.I have never ever seen anything like this before as a coin collector for so many years and I definely have no idea how did this "errors" appeared especially the LINES OVER THE ORIGINAL DIE.I also believe there is NO COUNTERFEIT COIN TO HAVE SUCH ERRORS LIKE THIS BECAUSE I HAVE SEEN MANY COUNTERFEIT COINS WITHOUT ANY TYPE OF ERROR.So,I need help from the coin experts to tell me this type of errors and explain in detail how did this errors appear on this coin,your help is very much apprieiciated as usual,hope to hear from you very soon.Please see the scans below and tell me what you think.Thanks alot.

Hi chinese item,

I think this coin is genuine!
I have also one dollar Yuan Shih Kai 1921 with "T" letter on obverse and on the reverse is very strong shade below the chinese word "Yuan". Take a look on my picture. I also have 10 cents Yuan Shih Kai with similar share on reverse. I noticed that you asked this question on many coin forums, like www.cointalk.com or some others. About this huge round and straight lines, I am not sure, but you can try contact with "expat" who is moderator on Russian coin forum: www.zeno.ru
"expat" is an expert from Beijing. He saw a lot of coins and he can help you if you will post your coin over there. But coin must be on white background, also show them edge of your coin. To register over there you will have to contact with "charm" (his name is Vladimir), his is a Russian guy and his owner and administator of the forum. Just send him email on charm@postman.ru and he will ask you to give yourself some nick name, after you will give him nickname, he will send you temporary password to login zeno.ru . Post later image of your coin there and "expat", "Chinasmith" and "Vincent" will help you for sure. If you are Chinese or can understand chinese you can contact also with other coin collectors from China at www.coinsky.com. Good luck my friend. Ohh, send greetings those guys from zeno.ru from me. I miss this forum very much
