it'll all depend on what you are looking for dawg. If you want errors and NIFC and clad commeratives, then look through every coin. I recommend this to anyone with under 1K of coins to search through a week for serious coin roll hunters where volume and silver is what matters, rim only if the coin looks dirty pull it out and look at it. I says it once and I says it again time is money; if you think an hour of your time is only worth ten bucks an hour, then just look through every coin cause you don't value time whereas if'n you think your time is worth hundreds of dollars an hour, rim search. keep the above in mind when consulting whether or not to rimsearch. EDIT: sound checking is dope to, but a good eye is betta than a good ear any day of any week of month of any year, ever.
