There are a million different combinations based on what type of coinage you have, and how close to an exact ounce you want to get. Basing my findings on the Red Book, here are some of the pure silver weights of common 90% coins (and the war nickels).
Dollar .77344 oz pure
Halve .36169 oz pure
Quarter .18084 oz pure
Dime .07234 oz pure
Nickel .05626 oz pure (war nickels only)
So you can figure it however you wish. It looks like a Dollar, Quarter, and War Nickel will put you about 1.010 oz which is quite close. Or within the same one-hundredth of an ounce a Dollar and 3 dimes is 0.990 There may be an even closer combination though, I don't know.

I don't know.... coincidentally I also bought my first pocket size jewelry scale on ebay. So we shall see. I know several guys who use them and they work great.
Of course like anything else, I'm sure some are better quality than others. |

What amazes me about those scales is that even the cheap ones seem to work just fine. I got the second cheapest one that I could find (I was too scared to buy the cheapest) and I don't have a single complaint about it.
As for silver weights, don't forget to factor in wear. Www.tulving.com for example estimates $1000 circulated face 90% coins to contain 715 Troy ounces of pure silver. Using coinflation numbers, $1000 face should have 723.39 Troy ounces of pure silver, but that only works for uncirculated coins. So about 1.1% of the silver in an average circulated 90% coin has been lost.
Using the above and average worn 90% coins, $1.40 face will get you almost exactly at 1 ounce ($1000/715). Using uncirculated coins, you would need $1.38 face to get one once (unfortunately an odd number). |

| I bought a few scales on eBay also. I have some of the higher end ones, but the cheap one I bought works just fine also. I used to sort my pennies using these scales before I got my Ryedale. $1.40 sounds about right to me. Each individual coin will have varying amounts of wear, so just pile your 90% dimes, quarters and halves on the scale until you get to 1.11111111111111111111111111111111111111111111111111111111111111111111111111 ounces. |
If your percentages are low.. just sort more. If your percentages are high.. just sort more.

Agreed but you may have to set your scale to grams and shoot for 34.5594444444444444444444444444444444444444444444444444444444 since I doubt a no frills scale will do Troy ounces.  |
