That is a strange looking coin. Seems very unlikely that there would only be grease all the way around the outside, while the centre was unaffected. My guess would be that this coin spend a significant amount of time mounted in a bezel or was subjected to some form of artificial wear and tear.

Pokermandude: it's unlikely, but possible. I've seen pics of LMC greasers having all the wording gone but the bust intact. SPP also has a 50-cent coin that is struck through with all the beads gone but the coat of arms largely intact. |

If there is lots of grease or other detritus of a greasy nature that interferes with the struck image, it will reasonably quickly travel towards the rim of the die, and thus preferentially affect the legends, rather than the central die features.
It has been quite a while since I have seen a coin this badly affected, but it seems to more often occur with smaller coins.
I would consider that this particular coin may have an increased value premium compared with other 'greasers'.

I think it is a very legitimate error... I love it...

The dollar is now in my possession. It is a very legitimate error. The weight is within RCM tolerances for nickel dollars, and I suspect this error is a die set-up strike (pressure test strike). Note the depth of detail in the deeper part of the dies (Queen's hair, gunnels of the canoe) and the lack of detail toward the rim (remember that the dies are slightly convex, which helps with high speed production. The coin is reeded, so the collar was fully engaged. I love it... soon it will find a place in my PCGS showcase of nickel dollar errors: http://www.pcgs.com/SetRegistry/sho...aspx?sc=1621Thanks again to Bill... a gentleman numismatist here at CCF.

Well, some input from the experts (thanks Fred and Mike) have told me that since this coin is fully reeded - it cannot be a die set-up strike. So, after a very light acetone dip, I can see it was struck by a filled die, possibly oil or water. The good news though, revealed by the acetone dip, is this was a proof like strike!! Very cool, as proof like errors in general, are quite rare.

It is NOT a die pressure trial.
The evidence for a die pressure trial (low pressure), can be found in the lack of detail of the high points in the design.
Queen's hair in this case is relatively well struck up. With low die pressure, the lower parts of the design are struck up, but not the high points.
With greasers, some of the detail on the die is filled in, and so that detail does not appear on the coin

Absolutely amazing how you guys can read coins, simply amazing.
my question is, how sure are you about your "readings"?
are there other possible options / answers?
just asking

If you go to Google images, search ' Grease Filled Die' and 'die pressure trial', you should find other examples pictured. (Google images is a very useful numismatic tool) |

So how does one distinguish such a coin being struck through grease/oil versus 'insufficient ram pressure', as shown at the bottom of this link: http://www.error-ref.com/weak_strik...rampressure/Both coins (the Andrew Jackson dollar and mine) share similar attributes...

What ever was on the obverse die or planchet (grease/water or both) caused this coin to strike up and look the way it does. Denticles on the reverse and nothing on the obverse tells me something interfered with the resistant pressure (anvil) IMHO
Wouldn't a lower pressure strike (with equally worn dies) show somewhat the same lack of design on both sides? - as opposed to one sharp die and one half worn, then one side would appear weaker although even pressure was applied.
just my opinion.

For a weak-strike vs struck-through debate I think we'd really need to see the rim/reeding. The article SPP linked to talks a lot about that.

Oh, it is definitely a strike-through. But hypothetically, if a coin like this did not have reeding (like our loons), it might be very difficult to determine the exact error...
Picture are forthcoming... I am just thrilled to have a Proof-like strike with an error like this!!
