Its an early baseline PIC (it doesn't even have on-chip brownout reset), in an obsolete pinout, so unless you want to practice your baseline PIC assembler skills on a breadboard, build an old project that uses it (or a 'C57), or repair something that uses it, that you can still get a firmware image for, its essentially useless.
OTOH, as they are only worth $0.85 USD each (from MicrochipDirect), it doesn't really matter. Maybe send them to anyone who's interested and will either pay postage or swap for something interesting.
Another idea would be to solder all the legs to a block of brass to stabilise them and try decapping the chip with boiling Rosin to look at the die.
