@ Jacinto
Welcome. For starter, I only trade against stamps with NO DAMAGE. No fold, no hole or part missing, no thinned stamps, no missing tooth, no rusting/foxing, no tear how small it is, etc. If you don't respect that rule, I will not trade with you ever again. As for my preferences: I don't want unsoakable self-adhesives off paper or CTO. I prefer used stamps over mint stamps as long as the cancel is not philatelic in nature like coming from a first day cover (and of course from CTO, again). Please don't send me mint stamps without gum as to me they count as damaged. Here is a list of what I would appreciate. Revenue stamps on documents!!! ♥️♥️♥️ (I am more than ready to trade directly with you for such material! Be sure to contact me first, even if you are reading this in passing.)
