Grading learning curve

How long did it take you to go from a beginner grader to where you are now? What are some of the tricks you've learned as you gained knowledge/experience?
For me, one of the things I've learned is to do is look at the coin in different light sources (when possible) and if in fluorescents always grade one less than what I think it is. I've also learned to bring my loupe with me and always give a coin a twice-over before considering it.

My goal is to assemble nice looking sets of coins regardless of grade, so maybe I'll never become an expert grader.
Obscurum per obscurius
I began 35 years ago and today 35 years later i am still a beginner. Never could get the hang of it other then the whole eye appeal thing and eye appeal is what i think it is all about.
"The silver is mine and the gold is mine,' declares the LORD GOD Almighty."
I had a tendency to focus too much on surface marks. I had to discipline myself to make an effort to put luster, strike, and eye appeal into the equation appropriately.
I frequently overlook hairlines. Even though I know it's a weak area for me, and I carefully rotate the coin around (then turn it 90 degrees and do it again), it's just something I don't always see. Hairlines count a lot, so be careful if you don't pick them up well.
Your first look at the coin should be without your loupe. If you use the loupe right off the bat, you might downgrade too much for surface marks which aren't as bad as they appear under magnification. Then when you take the loupe away, it's too late because you subconsciously have registered them as worse than they really are.
And someday I hope to be able to distinguish the difference between "friction" and "wear". Since I can't do that reliably, I can't buy raw Uncs which might actually be sliders (really nice Unc-looking coins which are really AU) if it would cost a lot of money to be wrong. (I guess that's not much of a tip.)
Remember to look at the edge.
Learn to recognize the look of dipped gold if you buy gold coins.
Of course, these are really mint state coin grading tips; grading circs is much easier.
Thanks to Mark Feld, Ken Krah and Disco Billy who taught us so diligently in the ANA grading class this summer.
New collectors, please educate yourself before spending money on coins; there are people who believe that using numismatic knowledge to rip the naïve is what this hobby is all about.
see? My Auctions "Got any 1800's gold?"
Like Shiro said, if the coin looks hot, I buy it and don't worry too much if I paid a few bucks too much for it.

A Tax is a fine for doing good.
I do a "first impression" grade by looking at the strike and eye appeal for a few seconds on each side. If it doesn't jump out as "69", the coin automatically goes in the roll (unless it's a cameo or Accented Hair). If it passes the first impression, than I check it under the loop. Any hairlines, any dings in the portrait or - on the reverse - the feathers or shield, it goes in the roll. Any field occlusions, it goes in the roll.
In other words, I rarely submit any non CAM or non Accented Hairs anymore. I do have one in right now, though, that if it doesn't score a 69, I'll know for sure PCGS is full of crap.

Copper gives me fits. Never will get it correct with them.

I also look at as many coins as possible via the internet and at shows. Since most of my buying is done via Ebay ect, you really have to study those scans to get a good idea. I might then copy the pic to a image editing program and then increase the size and look at the fine points while comparing the pic to a previously graded coin.
I'm still a beginner and concentrate on one series at a time, but from my interactions with my PCGS guy, I'm getting better!

I,m serious.
All the comments thus far are tremendous.Great thread.
On lighting: I think the best way to assurtain the actual grade is from `proper lighting` ie; the average white
lightbulb.These `normal` bulbs give off all the colors in the light spectrum more equally,where as a flourescent bulb is usually too `blue` or too `red`.
Summary: Flourescent bulbs suck for grading coins.
I'm flattered, but I would be completely and utterly lost trying to grade any other series. Frankly, late-date proof coinage is probably the easiest thing to learn to grade because it is subject to far fewer variables than earlier coins and business strikes. Right now, I'm having a hard enough time just trying to learn Walkers. They are much tougher than proof JFKs.
