First Head of Tiamat - particular summoning tome's very low value

[Gerhazo]

Description of Bug Experienced:
The summoning stream book "First Head of Tiamat" has a much lower value than all other summoning books.
Where the tomes usually have an item value (the one in the description and one used for determining what hagglers pay for them) of about 10000, this particular stream book only has "10", which seems like an oversight.

Steps to reproduce the Bug:

1. Find the First Head of Tiamat.
2. Examine the tome, notice the very low value of it.
3. Compare with any other tomes, which have a very high value.

Expected Result:
The book to be of the same value as others of its kind.

Actual Result:
The book in particular has a very low gold value.

This was far more annoying to fix than what I'd like - for so very little - , but fixed it is.
Locking and archiving.
