Why Cant I See These In Kr Books

Thanks so much for the quick ident.
My newest KR bood is the 2006, 33rd Edition.

I wonder why I got an appraisal of $8?
I see these coins for sale for $75 at http://www.worldwidetreasure.com/pr...number=05318
Is this place just a big rippoff or should I dump all of my old silver greek coins for scrap?

And yes, that site is a rip-off.

I know lots of sellers are big rip-off, like the ones on ebay who try to sell you coins in lots without showing pictures of the actual coins you will be getting. You know, sellers who sell lots priced at double what the coins in the listing picture are close to worth and then don't send coins even close to the ones pictured? Or sellers who don't tell what the silver content of coins in US/world silver coin lots will be, and want a big mark-up over what 90% bullion coins would sell for and then fill the lot with 50% silver coins? And how about sellers, who, on top their ridiculous markups for junk silver, charge outrageous shipping, sometimes over $20, for shipping in flat rate priority boxes? It's crazy out there, and we honest people need to stick together, don't we?

The Greek coin was from 1963and would be in the 1901-2000 Krause. It might be in the commemorative section--I found it online at world coin gallery. Always glad to help a fellow forum member!
