I highly recommend that method on Flowing Hair Silver Coins, I think it works wonders on making them shiny. Straight tip is what I think he used, I personally like using Phillips head screwdrivers when cleaning coins though.
Since you like that one here is another silver bars they are by the Lombardo mint of Canada Google Lombardo mint images for lots of their postage stamp Ingettes Lots of them on flea bay
Nice Numistamp Idhair! I picked one up a couple of months ago, but it was a Liberty Head Nickel. The artwork on them is very well done. I love the color and look of yours. Bruce
Counterstamps on Morgan Silver Dollars are a bit unusual, but not rare. This "N.S. & Co." stamp was a backstamp used by the Snellenberg Department Store in Philadelphia to mark cutlery that they retailed. Nathan Snellenberg founded the company in 1869 and it remained in business until 1962 when it closed. Starting in 1895 it opened a number of branch stores. There are about 15 or 16 examples documented, all on Morgans dated between 1878 and 1902. I always liked to think that they might have been used as "good-fors" and given to special customers as a promotion. I've seen no documentation to prove it, but it's a possible explanation. I vaguely remember Snellenberg's store when I was very young, so this has a special meaning to me. The coin itself isn't as dark as shown in the picture. I often darken my pictures to show the counterstamp better. Bruce
