What you guys think its worth? Has a potential error on the mint on the back. Might be a S over D or D over S under Microscope.
What Treashunt said. A 1914-D even in well circulated condition is very valuable. However, it appears this coin was etched to reveal the date, killing 80-90% of it's value. Someone might want it as a hole filler being a semi key date.
Etched with acid or vinegar to reveal the date. I'm not saying you did this, but someone did. The way you can tell is this. Dates on Buffaloes often get a lot of wear. The obverse of this coin is very very worn. The fact that you can barely see the date is an indication that this coin was dateless, someone put it in vinegar (or something else) and the date became readable. That is what I mean by etched, and it kills the value.
That is absolutely, most definitely a vinegar dated coin. I've been vinegar dating for quite a while, with hundreds of nickels going through my hands. It's nicely done, though, I've seen acid dates that looked horrendous.
