You have the yen confused with the Turkish Lira before the currency revaluation in the last few years. When the markets closed on Friday, the rate was ~¥115/US$1. A week ago the yen was at a multi-year high of more than ¥120/$1.
Your right Speedy, it's over in the General Discussion forum now. Roy said it didn't come up to the standards being set in this forum. It is good reading if you want to know what is considered a dollar and exactly what it is worth in silver content and value. So look for it over in the the General Discussion forum, but remember you have to sign in "special" in order to even enter this area. Threads title is "Golds real Value".
As already noted, the day is approching when paper money and coins are something you see in museums. Here we have those horrible toll boths on the roads that are being replaced with a thing called IPASS. That means no more coins there either. Not even a credit or debit card. Just a thing in your car that goes beep, beep and your paid up. I recently saw a vending machine that takes credit cards. True most fast food places take plastic nowadays. The greatest amount of stores and gas stations also take plastic. Saw my kid pull up to a gas pump, press a button, pump the gas, swipe a card at the pump, get in and drive away. I'm so old I remember gas station attendants that cleaned your windows. It won't be long when some kid says "hey Dad what is that stuff I heard old people talking about called CASH".
Your change from any $20 purchase would be one $10 Bill, one $5 Bill and two $1 coins. Not 17 Sacs. That would be like getting 17 one cent coins as change instead of one dime,one nickel and two cents.
Hey - if that makes you old what does it make me? I remember being a gas station attendant who cleaned windows.
More like a $10, a $5, and a $2 bill. No coins. If they discontinue dollar bills we WILL see two dollar bills become a LOT more common. But the original point is correct it would not mean you would get back a pocketful of coins.
Oh sometimes I do a funny jig trying to remember which pocket I stuck my bills in, but I never keep any currency in my wallet. I gave up keeping money in a wallet long before landing in NYC Catch your drift though
