The Official CONECA Handbook

The Official CONECA Handbook is approximately 150 -- 8-1/2 x 11 inch pages punched to fit into a loose leaf binder.  Much of what is in the handbook is now obsolete in terms of the CONECA then current administration, the Constitution and Bylaws and some of the programs that were current at the time.  Additionally, some of the more interesting articles in the handbook have been updated and included on the CONECA web site.

However, with that said, there is still a great deal of interesting reading in the handbook that many would benifit from.  To name a some: there are articles/features on wrong stock planchet error weights, the proofing process, bidding on coins at auction, coin storage tips, cleaning coins, mailing coins, what magnifier to use, U.S. coinage specifications, an illustrated chapter on the minting process, on illustrated chapter on "brief mint error descriptions," coin photography, etc.  All of these are subjects not yet placed on the web site that may be of interest.
