How much would I get to scrap my car?

I have a 1999 Ford Explorer XLT 4 door. It has 270,000 and the tranny slips and needs new brakes and wheel alignment and oil change and I don't think it's worth fixing up. How much would I get from a scrap yard for it?

02 Ford Explorer P0351 Error Code?

Check engine light just came up and this is the code I got. P0351: Ignition Coil "A" Circuit Primary/Secondary Malfunction

My car still runs just fine. No loss of power, no rough idle. So… Can I fix this myself and how?
