Dinky toys

Hi,

Whilst searching my loft (UK) I found some Dinky toys.

They are:

Shado 2 Mobile 353 - boxed - plastic box cover gone a slight yellow.
Missile works
UFO interceptor 351 , white missile, boxed, although plastic box cover is a
bit tatty
Eagle trasnporter 359 - boxed - box ok
Scorpion Tank 690 - boxed, complete with netting and shells, plastic box lid
split
Bell Police Helicopter 732 - boxed, complete with sign and traffic cone,
plastic lid is split

Firstly, is this the correct ng to ask some questions:

1. What the value of these?
2. Are they collectable or junk?

For more information I can be contacted  either via this NG or
[EMAIL PROTECTED]

thanks
