How much are vintage disney service pins worth?

[Sosai X]

I got these recently..

Both of these pins date to about 1972. On the left is an original one-year Disneyland service pin. On the back it's stamped with "© WDP STERLING". The pin on the right is the first WDW one-year service pin, and is backstamped "14K+" which I assume to mean it's 14 karat gold-filled. Since I am not a dedicated pin collector I have no idea what these would actually be worth today. Anyone have an idea, or know where I can find out their value? Thanks!

Not sure of the value of the one on the left but it is a cool pin.
