PC on 4 items

Read the guide here but still can't figure if these 4 items are worth anything. Can anyone please PC these for me? Thanks in advance.

portal = 5k or merch
turtle shell longbow = 15k max (tbh i would take any offer i get, starting from 1k)
gladius: no clue, fiery gladius go for 10-15k but this one i would merch
round shield = 50k i sold three of them for 50k each within 2min spamming kama

edit: didn't see it wasn't max, so def merch

Longbow is non-max and therefore for the merchant (even if it was max, it'd still be merchfood probably)
Gladius - short sword skin is for the merchant, Elonian skin (like the Fiery Gladius, but no flames) 8-10k

Shield is 65-70k easily, spam international HA, not Kamadan though.

Round shield 55k~ and the rest merch. Turtle Shell Bow is a very common drop from raptors so definitely salvage zealous mod
