I've seen something similar in the display of errors at the Royal Australian Mint, but never seen one for sale.

both those are very interesting!
It appears that feeders are made of softer metals to reduce die damage.

It's the wheel shown in Sap's post. It feeds the blank planchets into the coining press. As they say, it's all in the timing ... in this case, timing was a bit off.

Feeder fingers are similar to an open end wrench in appearance. They (or 'it' actually) moves a planchet from the feed tube to the collar. The four little holes are for alignment/attatchment, and the open end will push the planchet to the collar. Several different sizes will correspond to different sizes of planchets.

What you are seeing is examples of feeder finger misalignment, which will cause interesting errors on the coin as well. (You can just imagine what the coin looks like and will be called).

Here is a picture of what feeder fingers look like in a German press used at the Denver mint.

I am not sure exactly what that wheel in Sap's photos is, but it is not a feeder finger, and I note that he was careful not to describe it as such. They look like some type of timing gears to me.

OOPS........... the more I think about it, I'll bet that those wheels ARE in fact a design of feeder. What threw me was my perceived size of them. I would now venture to guess that these wheels may be in actuality, 16 or 18 inches in diameter.

I have seen a few of these at the shows and they are usually not cheap. I have also seen a Lincoln Cent struck on a nail embedded in a feeder finger! How the nail got in there is another question.

I guess that just proves there is a market for just about anything.

Prices on feeder fingers might come down a bit after the Chinese start putting them in large fake PCGS slabs.
