New to Coin Collecting and have somethings I have an dont know what they are!

I have a 1978 US Mint-Philadelphia Souvenir Set and was wondering its worth? I also have a "Department of the Treasury Bureau of the Mint" "Proof Edition" Gold Jimmy Carter coin, it has the eagle on the back and says " Inaugurated January 20,1977" and then a Jimmy Carter Quote, I will include a pic. Also, I have a AIR FORCE ONE ANDREWS AFB MD medal/coin, it is smooth on front and back but metal, on back it reads PRESIDENT OF THE UNITED STATES, AIR FORCE ONE. Again I will include a pic! Does anyone know what these things are all worth? I have other coins as well in my lot, you can email me at Do not include personal email address in post for your protection. with any answers!
