Collecting focus is great but I am personally not blessed with as much as I should have. If you enjoyed the pursuit and ownership while it lasted then don't beat yourself up for not being able to extract top dollar on the way out. My guess is these will do well overtime but maybe not as a bulk offload so close to your own purchase dates. Find enjoyment in selling them and enjoy the moment of clarity you have now that you know can part with them. If you are like me, it may not last!

I also like the idea of putting them aside for awhile if you can. I've found more than once I may be looking for items to purchase for a new project only to "find" some of them in my own "tagged for deaccession" bin
