Re: Types of numerals

As far as carrying coins around:  through college, I used to just drop
them in my front pocket - but through college, my trousers were almost
exclusively bluejeans.  Once I graduated and got a "real" job, I was
wearing slacks every day - and quickly found out that loose coins in
the pocket were far too jingly.  So these days I carry around a little
keychain-style change purse (e.g.
http://www.amcwholesaleinc.com/image/detail_274.jpg).  It holds a
reasonable number of coins as long as I stick to quarters and below;
but given the number of $1 bills I usually have in my billfold, I'd
need an entire second coin holder just for dollar coins if we made the
switch.
