The JOSEF VAJDAK Radioactive Species Collection was built over some 60 years of study and collecting in Josef's two main areas of interest: his native Pribram locality, where he grew up; and radioactive minerals in general. He spent decades exploring the old Pribram and Jachymov mines, and even found a new species at Jachymov which was named after him (Vajdakite). For the past 30-40 years, Josef has also been a mineral dealer, accumulating his own colelction while specializing in European classics and rare species through his dealership, Pequa Rare Minerals. This particular subcollection of his lifelong collection consists of a mix of both display-quality and reference-quality systematic examples (validated in many cases at the University of Vienna or by Josef's friends in the Czech geological survey). Additionally, many pieces were recently studied here in the USA at the University of Notre Dame. It numbers just about 90 specimens, as shown on the scans of his labels, below. I should note about those labels two points: firstly, that the prices are dated, mostly from the 1980s when he last valued them for his accounting; and secondly, that the prices reflect the quality of the mineral within in most cases (higher price equating to a better specimen).

Josef is over 80 now, and has finally let go of this collection with the hopes that it stays together and goes to a museum for research. I have agreed to offer it online, on his behalf. This collection represents THOUSANDS of hours of work and diligence. It is offered for the price of $7000 (click here to see his invoice to me, for this amount))
