How can I use a prefix to exclude a match?

Issue/Introduction
I have an Exact Data Match (EDM) profile that has as one column an account number. I am finding false positive matches in messages where there is a dollar amount that has the number string of a valid account number.
For example, the column has an account number of:
12345
And the email message says:
The cost of goods will be $12345.
I want to setup a condition that will "see" the dollar sign at the beginning of the match and exclude that match.
Can I do it?
Resolution
The string in a message:
The cost of goods will be $12345.
will be stripped to individual tokens:
The
cost
of
goods
will
be
12345
Our Detection Engine is seeing the tokens after they have been stripped, so we would only be matching against 12345, not $12345. Therefore, it is not possible to create an exception for a dollar amount.
