PCGS Variety Attribution Worth it?

I just had a question about PCGS Variety Attribution. Do they actually list the variety on the coin and is it worth the extra $20?

So the usual answer: It depends.
<< <i>PCGS Variety Attribution Worth it? >>
Depends on why you are asking. Is it a coin you want to sell? Is it a coin you want to have in one of your "Variety" Sets?
If answer to above questions are yes, then go for. If answers are "NO" then there are other options.

I agree if you are hard core into varieties then it is worth it. If the coin is just short term in your collection it's probably not worth it unless it is a rare variety worth a premium.
