Personally, I am going with the airtite holders, (20 bucks for $50) and then this case is nice...but it wont hold the territory/parks... i think that is a nice way to keep the coins fresh/safe and the case is easy to carry/and looks fantastic open or closed...it is a bit more...but worth it.
I would not eat the cost of submitting a coin to a grader (NGC PCGS) unless I thought the coin was going to be worth 3-4 times the grading cost... Just my opinion... Also, I know you already bought the set, but as common as these are you could pick them up graded for cheaper than you could send them in and get them graded... If you are just looking for cool ways to store them, you can actually buy generic slabs like this http://www.jpscorner.com/Slab_Style_Coin_Holders.htm#Slab_Holders and label them... This way they are protected and you can still get them out if you want... You are looking at about $1.75 each that way, so I'll add up too... if you order 50 or more, you get like a .35 discount on each... This is what I have done with all my un-certified Morgans... Or you could go with a nice Dansco like you mentioned Here are the part#s and prices from JPscorner 7143 7/8" Statehood Quarters 1999 - 2008 (100 Openings) $23.95 8143 7/8" Statehood Quarters 1999 - 2003 w/Proof $23.95 7144 5/8" Territorial Quarters 2009 P&D $18.95 http://www.jpscorner.com/Dansco_Coin_Albums.htm
