Question about colored Blood Album Vinyl

Quick question,I’m looking to purchase the blood type variant vinyls they are awesome,my question is about the serial numbering.The ran 500,then an additional 150,one of the vinyls I may purchase is numbered 655,anyone seen anything similar?I just found it odd but still love the records eitherways-l400

Oh, I didnt realize these were actually numbered. Mine are sealed and staying that way. Now I’m so curious what my numbers are.
But that is definitely a strange number for a limited to 650 release.
