Newbie Looking For Unsearched/Unresearched Coins

You'd have to find sources to buy unsearched coins from. However, those that know such sources aren't going to throw away their pay-day by telling another person interested in making a profit.

Your best bet is to get more knowledgeable so you can cherry-pick good deals.

This is a realistic goal, expressed in an unrealistic manner. You can't reasonably assume that whatever coin you might hold at the moment, has never been in the hand of someone who was seriously thinking about it before. The flipside of that is, whatever that previous person might have learned is not necessarily in the public domain, and they may not have gotten it right.

Every day, collectors find error and variety coins amidst coins which have undoubtedly been handled before (which is to say, all of them). Every day, someone puts an observation regarding a given coin into public, in a place like this, making that information forever accessible to future readers. Check out how effectively Google spiders CCF for confirmation, how many numismatic expressions link back to a thread here in a Google search.

So, the point is, whatever your goal - whether you're looking to buy random coins in the hope of nailing an extra-value variety, or just to contribute original research from an altruistic motivation - chances are you've a good shot at reaching that goal with whatever you buy.

bulk ebay, or any web deals "by the pound", can be a lot of fun and great for learning - but it will be something that you will likely be selling for a loss in the end (especially considering new higher shipping rates). most are parking meter/vending/counting machine rejects and will contain alot of duplicate generic coins.

stay away from "coins by the pound" if they are selling using stock photos (only buy if you are seeing the actual coins you are getting). don't expect any silver or anything really valuable (it happens but don't count on it)

I probably cycled through 25,000+ "unsearched" coins and had a lot of fun. if anything it enlightened me to what I liked and didn't like before I made any expensive errors.

best advise is to visit a dealer and dig through there bulk bins. pick out stuff that looks interesting and then go research it.

most of all, have fun, and be prepared to invest your $$$ and time - without expecting to get either of them back.

Not to far from reality. But not due to ignorance, just a thing with so many dealers. If you go to a World Coin show and ask for US coins, most dealers will say those are not welcome here. Or why would you want those anyway. Or against the law to deal with inferior products here.
However, your wrong as to what is available and coin shows in the US. At many coin shows I've seen World Coins, Indian arrows, jewlery, knives, books, coin Albums and Folders and so many other things I sometimes have to remind myseof what I'm here for.
