OMG 1,000!!!!!!! I try to sell them when I have my full 20 for the day, but sometimes I forget as it can take until early evening to get all of them, so then I wait until I get 40, but again that cycle continues. Once I hit 80, I DON'T forget and even if it's at 11p, I pull them out and sell them. LOL!!!!!!!
Once I get the Mansion it's going in the opposite corner on the top. Will probably take me a year.
10 Mil, same as the Mansion which is next on my "coin" list. I'm hoarding my gems for the Greenhouse.
