hi lakelover!
I never prepare a speech when I present tokens to anyone or even when I share my story as a speaker.
If you are spiritual, I would suggest that you take a few minutes before the meeting to quiet yourself, ask God to guide you and speak through you so that your husband's celebration can help another alcoholic.
My husband always come to see my get my birthday chips, but does not speak. He usually sits there and tries not to cry as my sponsor shares about us, lol.
So I would just share what it was like (for you and him, very briefly, nothing graphic), what happened (for you and him, briefly, nothing graphic) and what it is like now because of AA and the work he has done.
Congratulations to you both!! My husband and I are very happy today at 11 years married and my 2+ years of sobriety.
ETA: as an alcoholic, we like to hear the changes that others see in us, because sometimes it is not that clear to us.
