Plenty of these were owned by other well known figures in the mineralogy world, and while the boxes are a little shabby from storage, the labels are primarily intact keeping the specimens reasonably well labelled.
I’ve collected them all in a series of blog posts here, so you can take a look. I’ve tried to keep the prices down – specimens like this can fetch quite a price but hopefully these are somewhat more affordable. Click through to the listings, and let me know if you’d like any more photos.
