Routine to find exact Row matches in Col1 Col2 Col3 but exact offsetting numbers in Col4

[EagleOne]

2003

Need VBA (or whatever) routine to save to Sheet2 all rows on Sheet1 that have
exact row matches in ColA, ColB, ColC but offseting amounts in column D. i.e:

ColA ColB ColC ColD

abcd efgh ijkl 1,234,567.89
abcd efgh ijkl (1,234,567.89)

A sort would work for ColA, ColB, ColC, that said how to get the number offsets?

If someone has done this already, would you be willing to share that knowledge?

TIA
