Bars and rounds, it's always been bars and rounds, 1 to 5 oz with spot over 30. A 10oz bar is out of most people's price range making it a melt only piece ( they are always on sale with the big guys.)I sold some foreign coins that were either 92.3% silver, sterling silver, or some other circulated coins never intended for collectors that were either 50% or 80% silver. I took these coins to four different dealers and called another three or four and spoke to them over the phone without making the drive.
One dealer paid a little bit less than that day spot price for them,
while another dealer paid just a little more than spot because I also threw in various proof sets of foreign
{theoretically collectible} coins that included many non-silver coins.
I still think that .999 pure silver bullion in the form of 1 or 2 ounce coins
and 1 to 10 ounce bars is your best bet.
Unless you just enjoy the research behind coins, or you like to play the market with complex calculations of multiple variables,
and you see that as a hobby to derive pleasure from above and beyond how it may increase your wealth.
