    catching up

    in order for the united states of america to catch up foreign competitors on the bullion gold coins. .999999 fineness needed badly.............while face value need to increase too.

    .99999 is the same as having one steel cent in 2000 rolls of cents.

    .9999 is the same as having one steel cent in 200 rolls of cents, or 10 steel cents in 2000 rolls.

    Thus, there is a factor of 10x of "impurities" in .9999 vs .99999 but what's the practical difference? Even in a bucket of 100,000 cents it would be difficult to find the 10 steel ones.

    I wonder how much more it costs to refine .99999 gold than it costs to refine .9999 gold. (Probably more than the extra purity is worth.)

    it's pyschologically

    the dealers might imposed a little premium for .99999 over .9999 fineness of gold coin to their unknown customers.

    An extra fee only for their "unknown" customers? That just doesn't seem fair.

    not fair - yes

    because we as a collectors, we knew .99999 or .9999 or .999 are the same. that is only to make that coin look good and better.

    So that would be "unknowing" customers, not "unknown" customers?

    o.k. you're right.

    and those face value on the bullion coins. like $200.00, $100.00 or $50.00 on a one ounce gold coin are the same too.

    Speaking about gold, what was the purity of coins in the 1800's and prior to 1934? zg:goofer:

    Could it really be bent with strong teethe?????

    Marked - not bent. Teeth marks could be left in soft gold coins (or so the tale goes).

    A bit of confusion here - the reason for biting a coin was to see if it left marks. If it did, then the coin was suspsect. If it didn't then it was thought the coin was OK.

    I can tell you from personal experience however, I can leave teeth marks in a genuine gold coin. But I gotta bite really hard.

    That is funny. It went full circle when gold was used for fillings for teehe. So did the guy/gal who bit too hard end up with the gold anyways?? LOL,LOL aNYBODY REMEMBER gABBY hAYES AND ALL OF THOSE IN HIS GENRE?

    That's why it was used for fillings, crowns etc. - because it is hard enough, durable and doesn't react with all the stuff we put in our mouths.

    GD is right on this, when they bit a coin they were NOT biting down hard. They bit more softly and then looked for marks. They were not checking to see if the coin was gold, they were checking to see if it was gold plated lead. The lead being much softer than gold and much more easily marked.

    I too have tried biting a gold coins and I could also leave tooth morks if I bit down very hard. But you also are at a pretty good risk for broken teeth if you bite down that hard on them on a regular basis.
