Guys, this is a 1935 British Trade dolloar I found from a large lot bid just received from CNG. I found it to be a very rare one, but is it genuine? I can not find any problem with it. Anyone want to show his/her opinion on it?
I don't see any of the most typical hallmarks of the Chinese "replica factories", but I'd also like to know the weight. The correct 420 grain weight is 26.9568g. If the weight is right, and an in-hand inspection doesn't turn up any other questions, I'd be sending it to NCS for whatever they can do to stop that green spot from spreading, and possibly remove it. Much as I dislike slabbing, this is the kind of high value coin that I would very seriously consider sentencing to plastic prison.
Welcome aboard,Samwyi.The 1935 British Trade $1 coin is an extremely rare coin with 15 pieces recorded.You have to be extremely careful,as there are some very good forgeries. To tell the differences between the genuine coin & the dud,you have to look for these things - the weight.If it weighs less than the 26.9568 grammes,then it is a dud.Look at the colour of the piece,especially in the fields.If it has a soapy colour to it,then it is also a dud as well. The British Commonwealth coin & banknote market has generally strengthened across the board in the past few years. Aidan.
spiraltreet, satootoko and Aidan Work, thanks for the helps. I don't have an accurate scale at hand, the weight is about 27g. Aidan Work: When you say soapy color, do you mean "too smooth" or "colorful like soup bubble"? I observed both to some degree, please look at the photos. Honestly, I'm not quite confident with this coin, since it came with many common crowns. Even CNG (Classical Numismatic Group Inc.) might not notice this, the previous owner shouldn't have let such a good coin go away.

Aidan, I'm pretty sure it's not that color. I bought a more accurate digital scale, I'll see if the weight is correct once I get it. Really thank for you guys' help.
To me that example looks like all the random circulated examples (of common dates) I see, although the reverse corrosion looks a bit odd....
I'm considering to have it graded by PCGS, will the green spot make it a "problem coin" and not graded? Thanks.
Absolutely. The only top tier TPG that might grade that coin with the corrosion on it is ANACS. If NCS can successfully remove the corrosion, and it's genuine, NGC would probably grade it too.
I'll go to a local coin dealer and ask about his opinion first. This seems to be the first thing to do now.
Does anyone have conservation experience from NCS? I'm not sure whether conservation will degrade the coin? Thanks. How about first have it authenticated?
I'm not too sure but the last time I read some users sending their coins to NCS, NCS will give their opinion if they can do anything about a particular damage. If they think they can do it, most likely they might be able to do it unless they do specifically say no.
