Is my coin book odd?

I have the 2005 edition of 'Coins and Prices' and I looked up the price of my 1990 S, now it has a prestige set, and a non prestige set, and I don't think mine is a prestige set because it doesn't say prestige anywhere on it...so anyways, the non prestige set goes for 10.50...
Now, I then proceeded to look up every coin in the proof set
1990 S Half Dollar - $5
1990 S Quarter - $6
1990 S Dime - $2.75
1990 S Nickel - $5.50
1990 S Penny - $5.75
Total - $25
How can the coins in the proof set be worth more then the proof set?
Unless its a prestige set, which is says is valued at $32, but like I said, I don't think so...

There are many proof sets like this.
Where did you find those prices for the individual proof coins? Those prices seem very high and not in step with true market values. imo

1, The price of the proof set is for an average or typical set. Some of the coins in the set may be a little better than average, some a little worse. etc. The price of the individual coins is for a specific grade, possibly PF-67. This would be a group of coins that may be better than those found in the typical proof set.
2. Sale of a proof set represents the effort of marketing a single item. When you break up the set you now have to package, handle, and find buyer for not one item but five different items. Some of those items wil not move as rapidly as other and will sit in stock longer. This means money is tied up longer. To compensate for those differences a higher total price is justified.
Many things cost more for their parts than as a whole. A car is a collection of parts to which much labor has been added, but if you go out and price out what it would cost to buy all the parts to build your own car you will find it is considerably more than the cost of the completed car.
By the way, don't trust the prices quoted in any book for coins. The lead time for the book is such that there is no way the prices shown can be accurate to the market.
