That's funny.... I've had a workout home gym for years. In early days, I remember shopping for more 50's and 20s and looking for the low prices per pound. 
I prefer the bare metal plates over the plastic coated ones. The plastic coated ones are more slippery to handle.
Gnarls. 
I hate the new fad plastic/rubber coated ones, I have quite the shop gym and have multiple benches and racks so I need alot
