It‘s a chrome Schrader *.
What ? A dust cap? Maybe $0.10c. You can buy a box of 10 here in the UK for ?0.50p
The valve cap will set you back a whole 5 cents in Australia, the black plastic one is 2 cents. I would really spend up big on the 5 cent chrome one.
The local auto parts store sells them for 10 cents. Now, if it was from Casey Stoners bike AND was autographed AND was from Phillip Island last October, then I would give you $10 for it.
