US silver half dollars tend to have the lowest premium above spot price and tend to be least worn (closest to .729 troy oz per $1 face value) because they didn't circulate much. US silver dimes tend to be the most worn (possibly as little as .715 troy oz per $1 face value).
After you have as much as you think you might need for immediate purchases, then consider in which form you would like to preserve your savings. Even common date US Silver Dollar coins have numismatic value.
half dollars usually have the highest premium on junk, not the lowest. Overall, I'd say Rosie dimes would be your best bet for lowest price for most weight, followed by Washington. Don't by Walkers or Mercs as they'll have more wear. Generic silver rounds will give you more for your money than Eagles, but will be a bit harder to sell. You need to look up what APMEX is selling silver for, calculate the face value (15.9x, 16.3x) and then look around. Maybe you could find a slightly better deal here from a member, or keeping in mind the maximum bid, try ebay (don't forget to calculate s/h).
