Usually. A coin in Proof condition is almost always more valuable than the same coin in Uncirculated condition, but exceptions do exist.
I think that it depends on which is more scarce. The harder it is to find it then the more its worth. But in world trade i think that gold is worth more since we trade it.
No.

All proof silver dollars are silver dollars, but not all silver dollars are proofs. That's because proof coins are specially struck for collectors, while (at least up till 1935 in the US) regular silver dollars were struck for use in ordinary commerce. Please see the Related Question for more details.
it should be no more than 20 dollars
The 1st edition was the original therefore, it is worth much more than you though. The first edition of nightmare before Christmas rockets through the roof costing a shocking 100,000$.
Well, if it's not a first edition or signed, I fail to see why it would be worth any more than the retail price.
The Artists Proof (AP) is the first print that the print-maker makes to the standard the artist is happy with, all subsequent prints should reach this standard. AP's are therefore #0 in the edition and worth more (sometimes a little, sometimes a lot, depending on the artist) than the numbered limited edition prints that follow.
Artist proofs tend to be more valuble due to the fact there is usually only 1 or a couple, and the fact the artist printed it with his own hands.
yes
Coins in proof sets are generally worth a bit more than coins used in general circulation.
It depends on the book and the cover. First of all to have any real value it should be a first edition hard back. Paperbacks are not going to get as much money. The real money is in original copies for example a first edition hard back of the philosophers stone with signature could be worth £8000 or more!
About the same as any other yu gi oh card but it depends what card it is. For example if I had sorcerer of dark magic first edition it would cost a lot more than kuribo first edition.
Deluxe edition has more questions,so not worth buying if you already have the standard edition
Yes, silver is near record highs and in silver content alone a dime is worth close to $2, quarters close to $4.75 and half dollars close to $10. Of course, US proof sets are worth more to a collector than just the bullion value of the coins. But yes, silver proofs are worth much more than non-silver or 'clad' proof sets and proof sets are nearly always worth more than an uncirculated set of the same year.
The First Edition cards are more expensive because there are fewer of them. They only make one First Edition release and after that it's all unlimited. Fewer copies of something makes it more rare and hence, more valuable. Solution First Edition are somewhat more expensive because you get a little extra writing on the cards. Even from the original country Japan, they don't use 1st Edition cards because theirs no such thing. Either that or the cards I got were just Unlimited Edition Japanese cards anyway.
