What is the most expensive object on the game so far?

Thank you guys! Yesterday I saw a bed from Get Famous that costs 15000.

If you are talking strictly base-game, it's the Virtuoso Violin at 15,000 Simoleans.

Princess Cordelia's Gallon Bed is 12,000 Simoleans.

The Queen's King from the Get Famous pack is 15,000 Simoleans.

The Out of This World Desktop from Get To Work pack is 15,150 simoleans but it's a locked object.

I like to get the Mansion Baron aspiration on my rich sims so I am thinking about creating a painting and putting the value at 350,000 so they don't have to buy 10 Virtuoso Violins to make the house worth enough! I don't like my sims living in mansions, I prefer smaller houses so this aspiration becomes a pain to complete sometimes!

Off topic, but maybe this helps you @SimsLady2000 : You can place the vault from Get famous and fill it with 350,000 simoleons (or less, depending how much is missing to meet the house value goal). That will fulfill the aspiration goal.
