I won't do it for you yet. I'll just tell you how to do it. If you have 
trouble,  tell me in the thank-you note form below and I'll get back to 
you by email.  (BTW, I never charge any money since I do this for fun.)

Suppose all the replacing of the coins has been done and we have 50 coins
left to right numbered 1 through 50, some of each denomination of coin.

The coins numbered with multiples of 5 are half dollars.

The coins numbered with multiples of 4 which are not multiples of 5 are 
quarters.

The coins numbered with multiples of 3 which are not multiples of 5 or 4
are dimes.

The coins numbered with multiples of 2 which are not multiples of 5, 4 or 3
are nickels.

The rest are pennies.

Can you get it now?  If not, let me know and I'll help you.

Edwin
