David's cycleback book & website are very helpful. Also, after a few years of handling & studying cards, you'll find one of your most powerful authenticating tools will be your gut instinct. Your first instinct will be correct seemingly about 99% of the time. Always trust it, but of course verify if needed. I like to use David's print identification technique along with other checks. A good digital microscope is very handy to have around.
