It does vary - diapers are fifty cents unless they are perfectly like new and white, and then you might get a dollar. Bottles, same deal, perfect and white up to $2.50 each, but discolored or rubbed even a bit drops the price quite a bit (typically around $1 for nice ones, fifty cents if yellowed). Cribs (you mean playpens?) a few dollars each? Less if broken. Diaper boxes, same as diapers, if they are perfect and pristine up to $3, but ones that are squashed or torn are very common.
