I like the retro designs of silver rounds. Westminster is selling these:

Maybe it will never happen for the budget priced generic rounds, but I'd be thrilled to see higher relief silver rounds minted in the generics. The Walking Liberty design comes to mind right off the bat, reverse side with the eagle.
It passes the time, I guess, to pick up some rounds on occasion if you think in the long run that silver-price growth will exceed inflation and other benchmark metrics. Sale prices on silver are more to my liking for the accumulation phase.
