Q: What do you recommend to use as a finish if using these for coasters?

The best coating for coasters would be a 2-part resin. You'll get a glass like finish that is durable one it's fully cured. I would recommend practicing with resin if this is your first time using it. It is tricky and takes practice, but it's worth it.

Q: How heavy are these individually?

These are not that heavy it all. Maybe 1/4 lb-1/2 lb.

Q: What kind of wood is this?

I’m not sure what kind of wood it is but I will not purchase again. 75% of mine cracked not long after opening package. There are many reviews I see now that say the same thing. They are not drying wood properly.
