50 State Quarters Collection

I have been collecting the 50 State Quarters.
The photos of my collections can be found in my Flickr album. The attachments are some of them.

I used banks, vending machines to get coins -- instead of buying a complete souvenir set. This should be of more fun.

Now I'm still in short of:

1999			New Jersey(D)
2000
2001
2002	Ohio(D)
2003	Illinois(D)	Maine(D)
2004	Texax(D)
2005
2006			Colorado(D)	North Dakota(P, D)	South Dakota(D)
2007	Montana(D)	Washington(D)	Oklahoma(D)		Utah(D)
2008	New Mexico(D)			Alaska(D)
2009	Puerto Rico(P, D)	Guam(P, D)	American Samoa(P, D)	U.S. Virgin Islands(P, D)	Northern Mariana Islands(P)

Please contact me if you'd like to change coins with me!

Appendix:

There're total 112 different coins:

(50 + 1 + 5) x 2 = 112

50: Fifty States

1: District of Columbia

5: Five Territories (Puerto Rico, Guam, American Samoa, U.S. Virgin Islands and Northern Mariana Islands)

x 2: Half are from Philadelphia Mint, the other half are from Denver Mint. (Obverse, "P" or "D" under "IN GOD WE TRUST")

Theoretically, the expectation of the coins I should change is nearly 600, see Coupon collector's problem. But more than half of the coins I got were of the former series (with an Eagle on the reverse side).
