March '24 Update: Trading is turned back on. Woohoo!
Topps Baseball (flagship 1969-present) and now Topps Heritage Baseball 2018-present along with some oddball/food-issued cards. I'm also trying to complete my sets of older Topps football and baseball (1969-73) in NM condition (sorry for being a condition snob). Always happy to leave positive feedback.
I prefer to trade base cards for base cards and inserts for inserts. If my For Sale/Trade list has pre-1975 vintage or SPs or serial-#'s cards you want, I will trade them for pre-1975 vintage or SPs or low serial-#'s cards (mix or match) that I need, i.e. a pre-1975 vintage for SP or a SP for low SN or low SN for pre-1975 vintage, then offers will be happily be considered.
The bigger the trade, the better. :)
