3rare vintage DACTA LEGO SETS #1030

I need to get rid of these three vintage Lego sets they are complete they're not sealed but they are complete they're from 1980. originals. I'm asking $250 for all three or $100 a piece. just let me know and I'll change it if you don't want all three. I have lowered the price to $85 and the prices firm it's not going to go down anymore each one of these boxes is worth 100 or more
