Give them a little smooch on their little noses

But now there's anarchists in my group and they might find that offensive.

I would feel honored if anarchists thought my deeds merit an award even though we have differing views

Comrade Commendation? I can already hear some ultra lecturing you about power imbalance, hierarchy etc

but i guess you could nominate people and vote, form a committee haha, sounds like more work than its worth though

A no-bedtime pass?

Jk jk, maybe some zapatista stickers or pins from schoolsforchiapas?

Semi-serious, because I would like it: The most anarchic of creatures are the cat and the various cephalopods, and thus the highest awards possible are a lil' sleepy cat pin, octopus tentacle holding a hammer, or cuddlefish.

Despite it's later formalised royal moniker, the RNLI (Royal National Lifeboat Institution), formerly the National Institution for the Preservation of Life from Shipwreck, is still an independent volunteer force funded by charity. Kropotkin frequently cited it as an exemplar of free agreement and anarchist organisation, and rightly so. Crews who risk their lives or other people who contribute significantly are awarded medals, with almost 2500 given out over the last 200 years, and many more 'Letters of Appriciation'.

So maybe a lifeboat letter / medal?

(Yes, this was mostly just an excuse to talk about lifeboat history)

Thigh highs and a copy of The Dispossessed

The Disorder of Kropotkin (jk)

CNT-FAI must have had some medals in Revolutionary Catalonia? Where you'd find this documented though I do not know.

Honestly, you could just ask them. Let them know you hand out the medals for awards and put it to a vote if they mind it being an Order of Lenin medal or if they want something else or if they even care. That's probably what I'd do. Maybe first let them know that the medals are meant as a just for fun thing.
