There's probably more than $10 worth or parts in them that I can use. Just the channel select switch alone could be useful and probably cost me more if I were to buy one.
They're both AM and on FCC frequencies only unless they've been modified to suit the local market.
The channel switch will be an odd thing, the switch will output a series of N-Codes, quite what they'll be depends on the PLL inside the radio, some of them are straight binary but it may count up or down and will definitely have some odd gaps and swaps (for instance channel 3 and 4 are separated by 20KHz on the FCC bands so the N-Code will skip and again there's weirdness happens around channel 22-25 which means the codes reverse), some are BCD and will suffer the same skips and jumps as the binary ones, some will use the same codes as the 7 segment displays (ROM locked PLLs), others will use something different again (another ROM locked variant).
Not particularly easy to repurpose.
'old junk' if it's in good condition can fetch surprising amounts on eBay if it's in good condition, especially if it can be sold as tested.
Personally, they owe you nothing, scrap them for parts if you can't be bothered with testing and selling, if nothing else they'll be fun to take apart and work out the details of but I'm not sure what bits you'll harvest and find useful if you're not going to build more radio stuff.
