Absolutly Great Looking Collections Anthony & John !!!
TulsaBoy,
71 empty boxes show up from time to time, but are very sought after.
Usually to the tune of around 200.00-300.00 in ex. condition.
Very high grade examples could easily shoot up well above those figures.
High grade examples are extremely tough to come by showing up very rearly.
A minty box if ever found could easily approach the 500.00 range.
Here's a scan I took a few months back of a portion of my display box collection.
