I e-mailed you directly but I thought I'd post my thoughts here also. The strike you mentioned is retired now and I'd guess that if it hadn't been retired, it would have been changed. To the dismay of many non Nevada collectors, errors and short runs aren't as valuable as the Nevadas. I have seen an upswing in the prices of non Nevada strikes in the 3 years that we've been collecting.
Ebay is really our only source of information that we have to determine the values of non Nevada strikes and even that hasn't been too consistant. It all goes back to what a collector will pay to fill a hole in their collection.
