Birthday Presents?

I was on about a 2 year hiatus from GW and just came back. I found a bunch of birthday presents on all my characters, 1st, 2nd, 3rd, and 4th years.

How much are each of these worth?

I tried selling but no one seems interested, can other people even use my birthday presents or only me?
Also, anyone want to buy some birthday presents??

idk about 1 and 2, (better opened, imo) 3rd is i think 60-75k and 4th is 100k+(insert ecto number here) lol

4th years are 55k each

1 = 5k
2 = 10k
3 = 20k
4 = 55-60k

Those are the prices I have seen the most, and what actually sells. Personally have bought a few 4th years in the 50k range. And it is a very rare chance of getting anything decent, so the first and second are the ones I'd be more willing to sell as presents, not opened. You cannot even sell a white first year......
