2010 Red Book

Quantity of proofs minted. Note on the far right of each of those is price under the Proof grade also. This is the price of the proofs noted by the ( ). It is explained somewhere in the book but I never remember where. Read up on proofs and you might find that explanation.

FYI........ in about 9 or 10 weeks, the 2011 RedBook will be out for sale ! ......

(which is a leading reason why you must IGNORE the prices listed in there !)

I doubt it. The biggest difference will probably be the price of gold and silver as it relates to coin value. They used $800/oz in the 2010 RedBook, but gold is currently at $1100/oz. As long as you can make that rough adjustment in your head you really don't need a new RedBook every year. I've got the 2010 edition and I don't expect to get another one for 5-10 years.

LoL !

No, it will just have "current" information in there. Like any new coins/Sets, Commemoratives, etc..... that weren't in the last one.
True enough on gold & silver prices.....but even most of the other coins in there, the same theory applies really....the RedBook just isn't a good "price-list". It can be close on some things of course......but generally it's looked at to be "overestimated" when listing prices for coins. Consider them high when you look at that. (except for silver and gold.....there's just no way those price listings could ever be "current" from when this book goes to print/released.
The RedBook is VERY resourceful however for all of the "other" information listed therein. Mintage numbers, identification, compositions......etc. etc. This is why many collectors don't need to buy one "every year". Especially if they only collect "Classic" coins.
But, If you're an Ultra Modern coin collector......then it will show the newest/latest things in there

Proofs were minted in Philadelphia until 1964 and these coins had no mint mark.

No proofs were minted in 1965-1967.

Staring in 1968, proof mintage resumed for regular coinage (annual proof sets). All of these coins are from San Francisco and have an S mint mark (with the exception of a few errors).

Some special and commemorative proofs are still minted in Philadephia (with a P mint mark) and West Point (with a W mint mark).

As already noted the 2011 Red Book will be out soon. The way they issue a book almost a year in advance should really tell you how reliable the prices are. Probably a dream of one of the publishers or a list given to Whitman at a bar after a Christas party.
Remember that any price for anything in that book is made possibly a few years prior to publishing since it takes time to proof read, gather information on new items, acquire material for those books, then actually publishing them. Even distribution takes time so for all anyone knows the 2010 edition was started in 1948 right after the first edition.
To sum this all up remember that even dealers sell coins for much less or usually do anyway.
One more thing is I give about 10 copies of the ringed version away for Christmas presents each year along with a Uncirculated set from the Mint.
I've commented to the Publishers of Whitman about the silly dates on that book and was told by Dennis Tucker, Publisher of Whitman Books that since the first edition was made in 1946 and introduced as a 1947 Edition, that situation has just continued since then.
Possibly back then no one really knew if there would be a second edition anyway.
As usual the next edition for the 2011 version will probably be out in April, 2011.

If you are a serious collector, and need to "see' the details, on the different coins, I would locate, and but the "professional " RedBook". it shaws images in color, of all the know normal errors, and varietyies, (now 100%), and gives you much more info than the regular RedBook. I have both, and as a variety collector, it comes in very handy for linsoln, and IHC varieties, etc. I don't worry about prices. etc, so they don't HAVE to be current.
I might make a comment: If you are collecting RPM's, in particular, be aware that on the cents, at least, the MM is no longer placed by hand, on the hub, from 1990, on. So there are can be no no RPM's from 1990, on.
