I think so much depends on how your team in general was and how your boss thought of you. I think that in some workplaces where the team was good (sounds as if yours was) and folk were proud of their work, then it could be seen as a thoughtful gift, even if it slightly misses the mark.
I would tuck it away, as you have, but cherish the thought that you were a valued member of the team, they miss you (and thought you might miss the building!)
And a lot of these gifts depend on who has the responsibility and budget for them. A collection among colleagues will depend not only on how much they thought of you, but their disposable budget. This sounds more like a gift from 'management'. But, as ex-NHS, I would have been thrilled with anything from my employers! I deeply appreciated the small gifts, and buffet from my colleagues, but knew how tight their budgets were.
