The downside to being a box lot fan and not a worldwide collector is that I do end up with lots of stuff I don't collect. My preference is to trade these items. I have a few trading offers to put out there for anyone interested:
Random packets of worldwide (or maybe even country specific) that can include used or CTO or mix of both, I generally trade CTO at 2:1 for used stamps
Wantlist based trades via Scott catalogue numbers - there are some countries I have more of than others but willing to look for anything
Topic trades, my wanted topics for your desired topics
I have an embarrassing amount of duplicates but not all of it is well organized. Would welcome any one interested to message me and see what we can work out.
Collecting used Germany, Ireland, Scandinavia, Tonga (1960s/70s) and Austria. Owls and books on stamps, and Latin/South America issues from the American Bank Note Co. I also enjoy a fun gimmicky stamp, like the ones made from fabric for example.
