BPC sets....keep or toss

[pac.attack76]

My local thrift store had several priced at $4 and $6 and they didnt sell so when i pulled around back, i noticed 7 tv sets from the 90's stacked outside. A couple of 19" from 2001, a 19" Magnavox from 95, and orion from 98, two 13" sets and a little 9" from 85. I think it says TMK on the back. All work really well. Should i keeps these or are they just going to end up wasting space? Will they ever be collectible years from now like were seeing with the 80's and older sets?
