It's good that you ask, because I have thought about that too ...
The !BEER is ok to give I think, but the !DERANGED are meant for the ones who keep them and don't sell.
!MARLIANS and !shop - I have no idea, what they might be good for and who likes them.
So, I think it might be better to stop spamming with tokens and give only one or maybe two at a time.
