Yes, it was a nice surprise to coe up with something a little bit special. Don't know what to do about all the green crap on it though.

the green stuff definitely drops the grade a bit. The last "missing s" 74 I had, sold for about $45 on ebay and it was AUish. I have another I was going to list soon but haven't got around to it. I think the price estimate on coinsandcanada is quite low. |

Any suggestions for safely cleaning the coin - or do I leave it alone?

Thanks for the suggestion - already tried that. Soaked for a couple of minutes. Would a longer immersion time make a difference?

I've never used it myself, I'm just going off what others on CCF have said.

Nickel cancer all over this one. Even if you do remove it , coin will have pock marks. Too bad neat variety.

Was speaking with a friend today and he claimed to have similar stuff stuck to a coin he had and suggested it was because his coin was inside a leather purse for 30 years and the fibres of leather somehow attached to the coin and then deteriorated . . .

Nickel cancer? Never heard of that before but then I'm just learning. Isn't green more a copper oxidation thing?

Not gradable... that green crud is nickel (II) oxide... you can remove it, but you will have pits and craters in your coin...

Well that's Murphey's Law for you - out of a hundred coins most of which look close to uncirculated the only that had a shot at any additional value turns out to be ungradable . .  |

You might be able to make it more eye-appealing with a short soak in vinegar and using a cactus spine or hawthorn to remove the green crud... it is pure nickel, you 'd have to work pretty hard to hurt it (even more).
Prior to the corrosion, it looked like a decent, weakly struck, MS-63 example...

Thanks, I'll give that a try and repost a new photo if there is an improvement.

Did I hear nickel cancer?   I think we can come up with a more appropriate answer then that. |

Nickel cancer....oxide ...it is what it is. The coin is done like Thanksgiving dinner. Much the same as hard verdigris on a copper coin.
