SPECIAL FINE MINERAL AUCTION - JACK HALPERN COLLECTION - ends Thursday April 30th, 2020
POST-TUCSON SHOW SPECIAL – We obtained a large group of diverse beautiful specimens from the Jack Halpern Collection, built over decades by our friend in San Francisco. To spread them out more widely, we decided to let some of these, where he purchased them long ago at old prices, fly at auctions. Other specimens will soon appear in a special update on iRocks.com. For a new article on Jack, please visit our updated blog post: https://www.irocks.com/the-jack-halpern-collection (and we also have copies of previous published articles on the collection available upon request to those who win items here.) ; as well as The Mineralogical Record (https://mineralogicalrecord.com/labels.asp?colid=1550)
