A vintage baseball set collector for 40 plus years however I have started collecting modern San Francisco Giants HOF's and franchise players as well as modern versions of Mays, McCovey and Ted Williams.
I prefer post war cards to be crease free in the G to VGEX range and will accept lower conditions on pre war. My 60,70 vintage will be crease free otherwise I will let you know. I have vintage cards that have been appreciated but not always kept in sleeves and top loaders. Don't expect perfectly sharp corners but I will typically let you know if they are rounded or bent. I list cards I would have in my sets as a collector not an investor.
I typically prefer small trades that can be safely conducted PWE (typically 15 cards or less). While I have many cards listed on my waitlist I do not need to check them off in one trade. I have collecting priorities on which I focus and change over time. Additionally, how much fun would that be if you cleared your want list list all at once.
I crack every slab I get and I haven't ripped any wax since 1994 so I don't have much shiny stuff to trade but I am always looking to help a fellow collector out with their projects because that is what the hobby is about. While trading is a great way to enjoy the hobby, I am happy to sell cards at a fair price to fellow collectors.
