I wasn't able to find anything about a fridge, but some searching found a Sears catalog from 1959:

http://www.aei.org/publication/appliance-shopping-1959-vs-20...

From that page, it looks like the price of the washer, adjusted for inflation to 2016, is $1756.12. A comparable washer today, from Sears, appears to be somewhere in the $400 - $600 range, or about 30% as much as it used to cost.

Data for today's washers: http://www.sears.com/appliances-washers-top-load-washers/b-1...

And that modern washer would use less energy, water, and need less detergent, reducing the cost-per-load.

Modern washers use the same amount of water, except now you have to manually run the extra rinse program to remove all the detergent.

I'm from the US, bought some appliances a few years ago, and can confirm that $500 is about what you would expect to pay for a decent washer or dryer.
