Although the wiki reccomends people don't trade rims for den betas (cause most people are unlikley to accept) each den beta is worth about 10 - 30 den betas (depending on the one's being given). The  birthstones(excluding the month you are currently in) is worth a few rims (aka around 3 - 5) so you could possibly get about 3 den beta's from the whole collection, but you shouldn't really listen to me since that's just a little thing I thought about. (Also you might on get walls and floors at best for it).

I'm probs wrong doh :0
