Congrats on 60 days.
We only pass around the medallions for annual anniversaries. When someone celebrates an annual anniversary, the homegroup usually gets them a medallion. That person usually speaks at their homegroup the meeting following their actual anniversary. Another homegroup member presents them with their medallion and they open it up (we are a little superstitious about the person who is celebrating opens the plastic wrapper) and pass it around the room for everyone to pray over. It's pretty cool. (sometimes we have to track it down because someone doesn't understand what they are supposed to do and they don't pass it on. lol).
There are about as many different ways to celebrate clean time as there are addicts and groups.
