1913 S Type 2 Buffalo Acid Treated?

No, the coin has not been restored by any means. It is technically an original, but it looks like it may have been in the ground with one side up...possibly in sandy ground. That's why there is pitting much more so on the obverse. Being in that environment can expose all or parts of it to chemical reaction which is acidic in nature, so there is that. The coin may have been AT afterwards by somebody, but I am not sure of this. This year did occasionally have extravagant toning and toning streaks due to the planchets used.

All in all, I agree with the seller of an XF details grade, but the downgrade for the problems will bring varied opinions. I would give it a value of 250.

Just looks bad. Seller says that the picture doesn't do the coin justice....you can say that again.

Thanks all. You have added to my knowledge of what could cause this condition. I was never interested in bidding on this coin as I do not like it's appearance at any price.

I think so too. However, the date does appear to have some acid treatment done too. Regardless, this is sure one ugly coin. Sort of looks sick. I think I'd be afraid to touch it just, in case.

Definitely a pass on the '13-S.'
If YOU see something wrong with it, everyone else will see it too.
Save your money until an 'honest' example is found.
A lesson that took me years to learn.

Environmental damage and CLEANED, perhaps harshly, to remove the ED.

I've had a few of these myself that were dark and pitted and I managed to remove the dark, but not the pitting. It was probably pretty dull at some point and then polished. Then it toned or was made to tone.

If this guy was auctioning it he might get somewhere in the neighborhood of $100-150. You'd have to be loopy to give him his $375 asking price.

I wouldn't want the coin either, but I think y'all are being a but harsh. It is an "original date" and it does have a full horn. It's been through some stuff, but in the realm of bad, it's not that bad. One poster said "5-50 dollars"...do you have any idea what an original date 13-s type 2 looks like to be worth 5-50. I saw one once and it had half of one digit of date left, zero horn, was black and pitted except for the bad green corrosion on the surface....and it may have been slightly bent (couldn't tell for sure). I believe it went for $28 in a true auction.

I think if this coin were put up for a true auction, someone is going to see the full date, the full horn...and the generally XF details (while pitted and strangely colored) and it it will get bid up into the 200s.

I think this coin sells for 100-150 if it was restored, Steve.
