You have to get the royal crown from Tom Nook and then to duplicate it, follow these steps:
1. Take the crown to a friend's town.
2. Drop the crown somewhere
3. Tell Copper you want to go home.
4. Keep pressing home repeatedly until the menu comes up and press reset.
5. Start playing again and the crown will still be in your pocket.
6. Go to your friend's town and pick up the second crown.
The Royal Crown Does Nothing. It's Just Cool.
Um, what does that have to do with Animal Crossing? There is an accessory called a Royal Crown, but I don't think there is any brand of liquor called Crown Royal.
The Royal Crown appears rarely and randomly in the Able Sisters' shop, and can be bought for 1,200,000 bells.
for me it was April 20 2099
the code is 121D8E7E 00001406
1,200,000 bells (o_O)
Drop the royal crown in another friends town and speak to copper. Do the following: 1) Say 'I want to go home' 2) When Copper says: Well then (your name) then PRESS RESET! 3) If you timed it right, when you start the game again, your pockets should still have the royal crown in them and your friend should still have the royal crown in their town! 4) This can be repeated many times and the best thing is - Resetti won't bother you!
The royal crown will come out at a random time, just like any other shirt or accessory. There is no specific date or time that the royal crown will appear.
The Royal Crown 1.2 million bells
I think you just wear it I haven't got it though but I don't think it does anything!
The Royal Crown appears in the Able Sister's store on a random day during their business hours. There is no specific time to when the crown appears, so just keep checking their store in the hat section.
Well For My Game The Date Is September 20th 2009 that answer is wrong because on my game the date for the royal crown to be in able sisters is on May 15th 2009 Ive tried those dates, and I haven't seen the crown in both dates... are there any other dates for the crown/royal crown for me it was April 20 2099
