Displaying price limit above price slider scale

I'm working on adding a price slider to an existing price filter on an e-commerce shop that uses price buckets (predefined price ranges).

If the user selects any of the price buckets, the slider above would update as well (but we won't update it vice versa, for obvious reasons). However, for the last option, "above 50", I can't figure out a way to display this on the slider as it would be infinite. Any ideas on how the slider would display the last option?

P.S. We ruled out changing the last option to another price bucket as we can't dynamically define the buckets based on the most expensive item in the shop.
