Fred the other day you asked me if I knew where the slang BUCK came from for money... and I replied I knew PART of it.......
I wrote {i] Buck comes from the shortened word Sawbuck (use to place wood on for sawing)
A Sawbuck was a $10 bill
and a double Sawbuck was a $20 bill
finaly the shortened slang 'buck(s)' applied to any amount.
Well after one of those nightly trips to the oval office, I laid my head on the pillow and thought and way back in the dusty storage of my brain I REMEMBERED the OTHER part!
The sawbuck was pieces of wood put together to form an "X" (or a "sawhorse") and a log was laid across it lifting the end up for sawing. Sometimes a double sawbuck was used, one on each end of the log lifting the entire log. On the early $10's and $20's ROMAN NUMERALS were also used on the currency, X for ten and XX for twenty. That’s where the slang came from for the $10's & $20's it was the X's or Roman Numerals. It finally carried over to all money.

OK Robert Touts... AND NOW YOU KNOW THE REST OF THE STORY!

Note the time of this post... I did not want to forget it again! Whew! remembering THAT was like passing a peach seed!
