Hello I am very new to the coin hobby And I must say I’m loving it while going through a bunch of Bicentennial quarters I found one from Philly and it looks like it has a double die would you guys be able to confirm and let me know how rare it is and if I should get it graded ?
First, welcome to the neighborhood! Before you start looking for errors and varieties, you need to learn how dies are made and how coins are produced. Once you do that, take a few years to learn how to grade coins and whether or not it will be worthwhile to submit them to a TPGS. What you are doing now is putting the cart before the horse. ~ Chris
Looks like it is Machine Doubling (MD), happens when the die is not held firmly in place and it moves during the striking giving the flat shelf-like doubling that is not worth any premium. Welcome to CT.
Welcome to Coin Talk. In addition to what @cpm9ball said, there are multiple sites to help you learn. Check this one to learn about the coining process and it shows you the different kinds of doubling on coins: http://doubleddie.com/1801.html Researching your own coins is a fun part of collecting. Edit. If you're interested in looking for errors, this is a great site: http://www.error-ref.com/
As stated above, MD from a worn die. Note how flat and shelf-like the doubled areas are. Check some sites like http://www.doubleddie.com/144801.html and compare your coins to them. Welcome to CT BTW.

As the term suggests, it is the die that is doubled and then used to create thousands of coins. Closed quote
There are many types of doubling. Most are worthless. They are NAV or No Added Value Doubling coins. Yours is MD or Machine Doubling. It's very common so it is one form of NAV. As suggested above, take the time to learn as it can only benefit you. The more coin knowledge you possess, the better your collection will be. Welcome to CT.
