Can you add raw coins to the inventory?

After reading I don't think I can add my pregraded coins (raw) to the inventory. I wish I could because I'd like to show them but can't until they're graded which may be some time. I'm trying to get all commemoratives (early) with a grade of MS65 or greater. When I buy raw ones I do my best to grade them from the pictures which is tough and very unreliable. Wish me luck in the future with grading these commemoratives. BTW here's a Maine that I'm looking forward to getting graded.

I thought I'd include a list of recently acquired early commem's. They include the following:

1918 Illinois/Lincoln

1920 Maine

1925 Lexington

1952 CWBTW

1953S CWBTW

1946S BTW

1921 Pilgrim

1936 Cleveland

1925 Stone Mountain

1905 Lewis and Clark (regrade/crossover)

Just thought I'd include them.
