There's about 14.
They are oil stained and have been used as axle stands while working on cars for over 50 years. They would almost give off a lot of smoke if burned so they aren't suitable for that. They are various different woods and may carve - I don't know. If you have a use you're welcome to them.
MODNOTE - Please note these may give off dangerous gases if burnt. Further information available here..
