Okay guys, found this block this morning...
Am I correct in identifying it as a 554? OG all shiny and new on the back

Also, I have a quick question regarding how to label things....
Would this be considered a Plate Block of 10, or something else....I am trying to get sorted, and I'm not sure how to describe appropriately. I have read tons on the subject, but it's all a bit confusing. Right now I've been labeling with indicators like MNH, MH, MHH, MLH, and USED.
I want to get better at it, and I understand abbreviations, but I'm having trouble with knowing what is considered lightly hinged, or heavy, and so on....
Also, if I have a strip of three stamps perf. all around....do I call that a strip, or a block of three?
Eeeeek! It's so overwhelming.
Thanks again!
PS What do you guys think as far as value for this block?
