Can anyone tell me about these boards?

I came across 2 custom surfboards in my garage... I was wondering if anyone could tell me anything about them and maybe their possible value?
The first one is by Gordon & Smith. It's a longboard (9'0") and it reads "10015 Masi.Saili. 9'0" x 22.0 x 2.75 for Rod.Piazza." and has a signature on the center fin. See pictures below:




The second one is by Kaysen. It's a shortboard (6'8") and it reads "6'8" x 19 x 11.5 x 14.25 @ 2 3/8 for Henry Sieck" and appears to be signed by Chis Kaysen with "#654 / 7-92" written next to it. See pictures below:





Thanks in advance!
