Macro - changing value depending on the original value

liborpops

Hello,
Can you please kindly help me to avoid lots of slavish work?
I have a column where there are - among others - also cells with the following values:
$$$to be sent
$$$to be sent2
$$$to be sent3
$$$to be sent4
$$$to be sent5

The active cell is just in this column (the cell is selected). I want a macro which would change these values (nothing else) in THIS column into $$$sent, preserving the eventual number indexes (meaning "$$$to be sent" into "$$$sent", "$$$to be sent2" into "$$$sent2" ....... ). (The cells not containing any of the above values should be left intact).
Please ask me for more explanation if convenient.
Very many thanks in advance!
