So for me it's not just games I buy I'm also partial to buying the odd promotional item or collectors piece for my handhelds.
For the Atari Lynx I like to collect the Pin Badges (defi). So far I've, amast probably 2 thirds of all those released. Just recently I picked up the Official Club badge. You can see it on my quick You Tube video here:

I loo forward to seeign other peoples items.
I have a stack of these Lynx badges too!

Not sure how many exactly, I will need to find them, but I think it's about 20 odd.
I also have a few other bits and pieces like various Atari Lynx and Jaguar catalogues and a complete 2600 owners club pack that I am actually thinking of selling.
Another little item I have is an Atari 7800 Pac Pollux patch:

Came free with a limited edition of this homebrew game (only 15 numbered copies, I have no. 4)
I don't have much in way of this kind of stuff. I guess I have a few Lynx badges and a fair bit of merchandise tat. Lol.
I have uploaded some scans of Lynx flyers to the downloads section here!Â

Love that Frogger one!
I do as well. There were two other game boards a Donkey Kong and Galaxian. Wish I had the playing pieces for it.
