Next gen is now current gen, and the Xbox 360 and PlayStation 3 are old news. That directly translates into lost value on the second-hand market for those aging gaming machines.

United Kingdom-based CompareMyMobile.com, which buys and sells used electronics, collected a bunch of data about used-console sales in the U.K. The company found that, unsurprisingly, older systems are shedding their value as more people are trading them in.

The big losers? Sony’s PSP and the original launch version of the Xbox 360. The PlayStation Portable lost 72 percent of its value since January. The launch Xbox 360, meanwhile, lost 51 percent in the same period. The launch versions of the PlayStation 3 didn’t do much better. That console lost 44 percent of its value since the beginning of 2013.

On the other end of the spectrum, the PlayStation Vita with 3G, the 320GB PS3 Slim, and the 500GB PS3 Super Slim are all still worth more than $130 in trade-in value. Those Sony machines all outstrip the most valuable Microsoft machine, which is the 250GB Xbox 360 Slim. That box will get gamers $105 in trade-in value.

Again, this is just in the U.K. Demand for these console will vary in other territories.
