I've been searching bank rolls for 3 months since I retired. Have a bunch in flips. Mostly the ubiquitous flaws and errors that carry no premium. I have some in such good condition, they might be worth getting slabbed and put up for sale or auction. How did you start? Did you sell coins with the no-premium flaws and errors for 50 cents or a dollar? Did you get lucky and find a valuable coin in circulation? Did you buy coins at a low enough price to allow for resale at a higher price? Are you making a living selling coins? Or supplementing your income by even a small degree? Have you been searching bank rolls for so long that the mathematical probability is finally on your side and you periodically find a $500 or a $1000 coin? Of the options available, I'm wondering where to put more effort and where to put less effort. And which coins may provide a better chance at success; cents, nickels...etc. By reading about your experiences and how you got to where you are today, I'm hoping to gain knowledge and slightly more wisdom to help guide me down the coin path. My initial goal is to make a little beer money. Social Security is hard to live on. Thank you for taking the time to read this.
Welcome to CT. As long as you get coins at face value you are ahead of the game. Anything at hat price you can put up for sale on E-bay starting at .99, to see what happens. Dave
Keep your ear to the ground. Follow all the coin sites, and listen to the chatter of what new error coins might have been discovered that can be resold for a profit, eg. 2009 Skeleton Finger, 2015 Pump Handle. Last week on another forum a guy thought he had a new discovery error (2017-P Effigy Mounds quarter ). Turned out to be a false alarm. Still to buy a 100 coin bag of these from the mint only runs you a sawbuck over face. Very small investment.
If you plan on selling you might want to use a name other than "Coindoc". Welcome to CT http://www.coinweek.com/opinion/kaboom-an-update-about-last-weeks-article-on-coin-doctors/
Sometimes this works better, and certainly saves a lot of time. If you have, say, 6 Lincolns with various varieties or "errors," display your 6, but quote a price on "your choice of exactly 4 coins..." for $X. That lets the buyer avoid two items he already has, or does not want, or does not like, but still results in an efficient sale of 4 at a time, saving both time and postage. Ebay probably won't let you do this, but Coin Talk might. And the coins don't have to be all-Lincolns, for instance, but they do need to be the same appoximate value, or someone will always take the 4 best pieces, whether he needs them or not. The buyer communicates to you, "I'll take A, B, D, and F..." Yes, different buyers may want different "4" coins, but that doesn't matter; what matters is "I'll take........" Leftovers go into the next batch.
