I just lost mine after getting an error and having to refresh the page lol.. I made it up to Stage 8 and was working on getting upgrades since my stamina would drain pretty quick, so I'm not entirely sure how much gold I had by the time it reset. I know the workers\managers was fairly far down since at least 1 unlock for 2 more managers needed me to complete Stage 8. I'm pretty sure the wet side might have been to the point there was a red gem upgrade to have packs drip that I don't think I was able to buy, and the right-side upgrades I made it a little passed the fireworks upgrade, the upwards lightning path went to where most upgrades were starting around 800~ gold I think, although if I have to grind a bit then that is okay with me. As for Secret rares I had the regular 1-7 and the other special card I had for Stages 2, 4, and 5
I had the game open overnight so I didn't have any progress on the most recent update since I wasn't playing on that version
edit: I use the same username on Discord as I do here in case you don't want to paste the save file in the comments here, I couldn't figure out how to message on here if it is even possible lol
