In the case of Australian QSA's, is it not perhaps a matter of supply and demand, coupled with the justifiable immense pride that Australians have in their military history?
The same can be said about Canadian medals..... They are getting harder and harder to find..... But occasionally a good one shows up..... I was contacted by a collector the other day who had obtained a previously unknown Raised Date to the Strathcona's...... That now makes 50 known to the Strath's and 8 to others for a total of 58....
