Tantalum capacitor scrap

I'm having the hardest time telling the difference between these three types:
"Hermetic Capacitors - $24.25/Lb
Wet Tantalum Capacitors - $50/Lb
Ag/Ta Capacitors - $90/Lb"

I will attach pictures of three types of caps I found today, can you please help me identify type? There are two pics of each cap and I tried to get all the numbers on them. I am hoping I finally found one of the elusive silver ones!!

I think this is a hermetic tantalum cap:







I think this one is a wet tantalum cap??





I THINK this is a Ag/Ta Cap?? pretty please?!

Hello --

The top three pictures are Hermetic Capacitors -- The second set of pictures I actually believe are Aluminum Capacitors and not Tantalum at all, You would be able to figure the difference by the difference in weight of the hermetic and the second set.

The Third set is Ag/Tantalum Capacitors.

Thank you!! Is it the SHAPE, the crimps on each end, that lets you know the last set of pics is silver?

-And the second two pics are the same capacitor, just different numbers and it is quite heavy. With the one crimp I thought it might be a wet Tantalum cap instead of just a hermetic?
