Pretty clever theme, the money thing. I don't know whether the $1,000 and the $10,000 have ever been in general circulation in the U.S., but I still remember them from my youth, when I had a fascination with the large bills. It's just too bad that Mr. Mausser couldn't cram in a Wilson100000.
The fill seemed generally decent. Frannie didn't like the awkwardness of AGEONE (11D: Time of first steps, often), and I thought the same of PLAYON (13D: Not stop a musical gig), but the majority of it was fine. I enjoyed 41D: Check the figures? (OGLE), even though it was right next to one of the least-ogle-able figures in all of cartoondom, OLIVEOYL (40D: Toon with 14-AAAAAA shoes).
I liked the contemporizing of OCCUPY (46A: Modern protest name) and IRS (65D: Org. in a 2013 scandal), and 60A: HI-strung instrument (UKE) was cute. I didn't know that there was a place called Acre in ISR, so it's lucky that we knew that the ISERE was 14A: Grenoble's river. We haven't seen Grenoble, but we have seen the Isère where it starts, high in the Alps. Nevermind the skiing, Val d'Isère is beautiful in the summertime. Makes me want to start looking at airfares just thinking about it!
