Errors and varieties thickens your blood. if you can survive in that arena, you can survive just about anywhere in collectibles.
People have used scanners, a cheap 40-60 dollar microscope, expensive microscopes, a digital camera with at least 8 megapixels, and some have been quite creative. The type of tool you want to investment is one you can afford and feel comfortable using. I personally use 2 different
AmScope stereo microscopes, one cost me 145 bucks, the other well over 4 times that. I've invested alot in the equipment and continue to do so because it makes finding the varieties and errors alor easier. With the microscopes my son and I managed to pull out every single 1972 doubled die out of two 1972 5,000 count bag and by doing so, maybe our money back and a good fistful of profit. With my choice - the microscope, I can usually go through a LOT of coins in a short period of time, with the right lighting its easier on the eyes and you only need a stereo microscope that goes from say 3.5x up to 30-40x. To me anything higher than that is a waste. You might be able to find a microscope at a thrift shop or other location at a decent price.
Most of the community here is willing to help and provide guidance when we can. I am straight up, I won't sugar coat something when it comes to collectibles. You'll hear the blunt truth from me 90% of the time. If I don't know, I will say exactly that. I don't know it all, and we all learn something new each day. So DON'T get frustrated. many of us have websites or even examples of coins to show in order to make the searching a little more fun and comfortable.
In our last post, it seems like you already have a good start on categorizing your collection. Its important to put a side a few of the exmples and feel free to refer to them to see if what is in your hand resembles the reference. You hit it right on the head - the better the pictures, the more likely we can give you our best educated guess of what that coin is. Coop is an highly educated and informative mentor on this site, amongst many others. All will offer encouragement and advice, but its up to you to keep your head up and keep looking for those elusive coins. Being diligent and persistent will pay off - sooner or later ! = )
I like cents. So, I will research a year I want to buy rolls or bags of that year and mintmark. I will look over the websites that offer educational material, like
http://www.coppercoins.com and
http://www.doubleddie.com and look over what type of varieties are in that year/mintmark. People will buy from
ebay alot, and the only encouragement I can give to you on that is this advice - If you buy from
ebay, try to find a buyer who isn't a coin dealer, and that sells alot of different items. If they sell a limited amount of coins, there is a SLIGHT chance that they may have not searched through coins to pull out any potential varieties. so some one who might be a pawn broker on
ebay, or sells toys, coins, dishes and other collectibles might be a good choice.
I've been doing collectibles and coins for well over 35 years, and it still humbles me every once in a while. The BIGGEST thing to remember is, if the potential error / variety shows some sort of marker (ie die gouge or whatever) look for those first. Not all of them will show every marker - some may not show any markers at all. In the past year, I have been blessed - I have made purchases of penny bags that have over-produced varieties. But, on the "free" side of the house, the Penny Boxes I get from the banks tend to be - in Coop's infamous words - "Duds". So, I stick to what I know how to do, and thats find a reputable seller, haggle prices and if the lead produces, keep purchasing what you can afford.
Keep Searching when you have the time and desire. Good Luck !
