That is split plating. It's very common on copper plated zinc cents(1982-onward) and for some reason it's particularly common on 1992-Ds. I've gone through entire rolls of '92-D where almost all the coins exhibited this. Not really any value, but that's a nice example and a good "keeper" as an example.
Here's a link that explains it a little further(notice that the top coin photographed is a '92D)- http://www.error-ref.com/split-peeling-plating/
If you look at the top photograph of the OPs coin, you'll see it best at the top and right edges of the Memorial Building. The thin copper plating has split, revealing the zinc core.
OP, If a coin (any coin) was a genuine error but had no real value, would it still interest you? Also, while off-topic, this might be of some help to you. http://www.lincolncentresource.com/smalldates/1970Ssmalldate.html
As for that '86D, it appears to have had the copper plating removed via electrolysis. These can be tough to distinguish from partially plated cents without an in-hand examination of the coin. http://www.lincolncentforum.com/for...incolns-(altered-post-Mint)&highlight=partial
