Any Tips On Identifying Scott 6107 - 6112

Seems Linn's is a bit late in helping us easily identify the usual subtle differences on these new US definitive issues , in the case the June 9th American Icons Flag stamps.

I see the usual USPS micro imprinting going from one side to the other on the flag bottom on most. I use the wonderful Jim Bardo dealer site to help on these pretty simple methods. Thanks in advance Jim!

Specifically though , how to distinguish 6111 and 6112 from their look similar coil counterparts that have just right and left only booklet perfs ? Is it just a matter of perf size or type to help ?
