I find the Lincoln image in the building on the reversed side. I can find it. Is this normal for this coin?
I assume you are saying that lincoln is missing from the memorial on the reverse? You can try over at http://www.lincolncentresource.com - there are some help people over there also.
One thing you have to keep in mind about smaller coins like the Lincoln is that it doesn't take much grease or debris to fill a recess of a device on a die and make it "disappear" on the coin. Chris
