2009 $1 Coin Multiple Die Chips

Hey everyone,

Found this coin and wondering if anyone encounter this multiple die chips before or could shed some light if this is a common or rare error.

Please note that these photos are taken while the coin is in a 2x2.

There is 3 chips on the reverse, and there is another possible 4th small chip on the left side of chair "Between small girl and old lady sitting on the chair" it's a pretty small so could not confirm at this point.





On the observe side, there is a chip on the queen's nose. Looked like she got a mole





I suspect that there is also minor rotated/upset error(10-20 degree) on this coin however I'm not sure how to check it. Could someone shed some light on this too please.

I am planning to keep this coin in my collection because it's my first encounter with so many die chips error and it's in a good condition after 9 years in circulation. However I am also curious if I plan to trade or sell this coin, what would be a fair value?

Thanks everyone for your time
