Buying Silver/Gold Coins and nuggets'

I am looking for some coin’s from late 1700 to early 1900. I would like to get a few 0.03, 0.02, half penny/dime’s. Oh almost forgot one or two 0.20 cent’s one’s too. From VG to EX Fine, if they are not to expensive.
I would pay 90% of spot for a couple of gold nuggets’. A gram of two.
