To get this, go into your career and level up your society. Each level costs more than the last. You start at 1, so you can go up 9 more levels.
I don't remember what each level is, but I know that:
Level 2 = 200
Level 3 = 400
...
Level 8 = 3200
Level 9 = 4000
Level 10 = 5000
You probably need around 20,000 coins all told to reach level 10.
Coins can be farmed if you have alt accounts. Each alt can net you about 8100 by running through a series of 6 specific courses. In order for a course to have challenges that earn you coins, it has to have enough plays, so look for the courses with 300+ plays.
Note that in order to actually USE the coins, the alts should all put the coins into your club. Then you should close the club and make an easy event for yourself with the purse consisting of all your coins (100,000 maximum per event). That's the only way to actually transfer coins from one player to another.
Gottle has a lot of courses, but 4 of them are ones you want in particular. Remember to look for the ones with over 300 plays.
-18 aces
-9 aces
-Money10
-Money10 (yes, there are two with the same name)
The other two courses are called "Nine Holes in One" and "18 in 1". Both are by the same designer, so if you search for the first and look under "More By Designer" you'll find the other.
Each of these courses are tap-in holes-in-one. 72 taps total = 8100 coins. Do that with around 5 alts, and you can earn all three of these achievements:
In addition, 2 of these courses will automatically net you this one:
Finally, if you have 125 alts lying around (don't laugh), you can go for the big one. (Obviously this works better in groups.)
Best of luck!
