Reeded edge question ????

[Dozer D]

I know that the weight of the mercury dime vs the roosie's are the same, but is the number of reeded edges (groves on the rim) the same on both coins? Same question on quarters (SLQ vs Washington), and halves (Ben vs Kennedy)?

Looked up the dimes. Both have 118 edge reeds.
