Set of 130 (1-130)
I would assume that this series starts at #1, because it probably does not continue on from the Peanuts Brilliant Frogs Limited Edition Series 1 series, as I have seen the same numbers in both series.
This series also has a hammerhead shark after the 'Limited Edition Series 1' text on the back, which was not present on the other set.
I don't know whether, like that set, different coloured backs and/or different cut patterns are available in this series.
Lastly, I have seen evidence of numbers up to #129, but do not know how many are in the base set, but it is assumed to be 130.
I'm currently running some final tests etc, but everything should be working as expected - Please let me know if you have any issues!
