Is it worth getting getting CU partial ladders graded and if so, which TPG? Series 2009 234567xx and 2345678x I'm guessing they are both a minimum of 64. I have years of experience with coins and know my way around MS slabs but not much with Unc Paper. Thanks
No..it is not worth it at all. It has to be a full complete ladder! Partial Ladders are not considered a fancy serial number.
Very minimal collector interest in partial ladders, and you will likely never see them at major auction houses like Heritage, Spink, Stacks, Lynn Knight, etc. You will typically see them on eBay.
