Over Sized? 1928 Valley Forge Block Of 4

Good morning everyone.I have a quick question here in regards to the size of these stamps..these are much longer than any of my other blocks and I was wondering if this is a error or very rare or very common ect..
Just wanted to ask to see if my hunch is right because I am starting to look much harder at all of my stamps for ANY type of oddity(s)
Made a side bet with the miss'es on this one so HOPEFULLY you guys help me out hehehe!

Not sure what you mean by longer. The two tabs at the bottom are part of the normal selvage on the full pane. It should be retained and preserved because of the plate number, which adds a small amount of value.

This is not a complete plate block for this stamp; it should be six stamps, the bottom three with tabs (like yours), with the plate number on the center tab for symmetry. Years ago, the (flat-plate) blocks of FOUR with a number were called "poor man's plate blocks."

Your wife wins this one.

Much appreciated Doug..just had to ask to be 100% certain
