Sometimes, yes, because they were cheap and/or ignored. @C-B-D buys details coins as well and flips them the same way. I also buy a lot of problem-free stuff as well, and market it as such. I ALWAYS describe any problem a coin has, from hits to cleaning to scratches, no matter how insignificant the problem is. Not my problem if the buyer chooses to ignore my statements or think the coin is worth my asking price. I just sold a cleaned AU seated dime, explicitly described as such. I bought it hoping it was problem-free (bad picture gamble), so I only made a few dollars above breaking even. My goal was to get an offer that would allow me to break even, but someone bought it at the asking price. I'm not out to unscrupulously siphon away collectors' money. I'm just trying to make an honest buck buying and selling coins. If I make a mistake and pay too much for a problem coin and can't return it, I'd rather lose money than hide the problem.
RIP me. The reason I said that is because several of them are very marketable in the raw state, and with my need for a quick turnaround, I don't see the value of tying up the extra money for a marginal increase in selling price. Some are more-easily sold certified (crusty original AU busties, AU/MS 3¢, and AU/MS seated half dimes and dimes, for example) and are worth the cost of grading if obtained for cheap enough.
This looks like one of my usual hauls from the local coin show to peddle- sans all the bust coinage. I feel that originality and eye appeal are the best characteristics, if you want to build clientele. To each his own, but i like 2 sell coins, that i dont mind hanging onto if they dont sell. On the flipside, i like to purchase coins from dealers (even CT members) that have an eye for quality. It sorta works both ways imo
I personally like the early 1800's coins. Something about the history, people who may have handled these coins. All that has happened during themyears since. Goosebumps when holding one of these. Just super nice. I couldn't even really give a good guess at their grades. Just nice to have.
