Is it possible to find the actual Pop Report of Cards but years backwards?
Used Sides that show older Sides, but when i use them it didnt work out for The Pop Report.
If its possible what Side/Program you are using?
started over a year ago with something i like to keep an eye on, but would like to have a better overlook what happens in the big timeperiod before.
very grateful for help 
Amazing Site =)
Unluckily theres no vending Series 1998? ( The 1 2 3 Series) ( I hope iam not blind)
In case iam blind iam sorry
Otherwise any Chance to get the Data? Different Solution?
You’re not blind, pokemonprice.com sadly lacks the data for non-promo Japanese sets. However, @pichufan is currently looking for beta testers for a site/program he created that’s supposed to track PSA pop development history:
www.elitefourum.com/t/pokemetrics-thread/32484/1
Don’t know if it includes all Japanese sets, but I guess you could shoot him a message and try it for yourself 
Thanks for the tag @muk . The data I have only currently goes back to the end of 2019 and I only show the past 12 months, but it sounds like OP is after something a bit further back than that.
I’ve just been sharing the direct link to people as I think it’s relatively bug free (there’s a larger issue with some of the newer sets but I should have that fixed tomorrow with any luck), if you’re interested you can access it at pokemetrics.org. I believe Vending Series 1 is this one, but PSA’s naming is a bit iffy on these.
