I think it's safe to say the left coin is fake. The Boo isn't even close to the style used, and there are many other problems with the calligraphy.
The right coin is questionable too. It's Board of Revenue, but with a 1 dot square head tong, which is not listed in Hartill or on Zeno. Also the radical on Dao is not correct.
