AWK: add suffix to one column and print out all

Raw data look like:

1 | Field1 | Field2 | Field3
2 | Field1 | Field2 | Field3
3 | Field1 | Field2 | Field3
4 | Field1 | Field2 | Field3
5 | Field1 | Field2 | Field3
6 | Field1 | Field2 | Field3

Want to change it to:

1 | Field1 | Field2$ | Field3
2 | Field1 | Field2$ | Field3
3 | Field1 | Field2$ | Field3
4 | Field1 | Field2$ | Field3
5 | Field1 | Field2$ | Field3
6 | Field1 | Field2$ | Field3

All I need to do is:

cat input.file | awk -F"|"  '$3=$3"$"; print'  >  outcome.file
