How common is this...

So I have a game bat of Todd Greene. It has his name and and number on the knob and is a Rawings with a dark blue ring around it. Now the strange thing is this -- the knob is stamped Mac25 and has a batch number of what looks like 570 and a year stamp of 97. My question is is this common or is this a pretty rare thing ?

The "MAC25" models started in 97 and used to be "256B" model bats which McGwire used exclusively. Greene probably used 256B model bats too which is why his bats have the new model number MAC25 starting in 97.
