i would donate it to any organization that has a thrift store, or to the guild, senior center, local long-term care facility, school art department....
there are lots of places/people who put to good use things we no longer need. i would never just throw one away...even if it was broke i would find a way to salvage as much of it as possible and donate it.
thats just me, i don't throw away anything i think someone else could put to use; i pass it on instead of filling landfills.
