I’ve updated the list. Looks like untracked it is fairy cheap to post to the USA, sending them tracked is going to be prohibitive though takes it up to £8 , untracked is as low as £1.50.
If you guys find the post is too expensive please don’t do post them, it is just not worth it and I’d feel really bad too lol.
I can get mine into a ‘thin letter’ category (in a slice of cardboard with tape all over, no wrapping) you may also be able to get away with a letter size?I know contactcr said it would be like $1.15 – $1.36 USD depending on if you choose “rigid” envelope contents for <1 OZ (so ~3 quarters).
My limit for thin letter is up to 100g , 5mm thick, Minimum size: One surface must be at least 9cm x 14cm, Max length: 24cm Max width: 16.5cm delivery is 6/7 days is £2.30 or £1.50 for around a month delivery.
Looks like this would be doable, from my end anyway - and if you don’t want to swap I’ll obviously pay the postage up to about the same price in dollars. 
I was thinking as I have around 20 old halfpenny’s if you wanted to swap maybe I have your year of birth if you’d like? along with some other coins too. Just let me know when you’re ready to go
