What would you all recommend in terms of which coins to buy (online, where you can't see the actual coins)? Dimes kind of scare me off as I would imagine them to have more wear meaning every $1 may be lower than the normal "circulated" .715 toz. Halves sound the best by far from that perspective. And better condition can never hurt even aside from the weight consideration. However, their value is not as easily divisible (~$10 vs. ~$2).
Would a majority of halves and a lesser amount of quarters and dimes make sense? Like 80%, 10%, 10%? Also, with what I'm looking into, there is the possibility of getting some older coins mixed in (Franklins, Walkers, Mercs, etc.). This doesn't really affect my decision at this point, but maybe some of you could give me a tip if you think it should.
Thanks.
