Patti,
In 1912 1st class rate was around $3000, a little up or down(that would be $60,000 in todays market). And a third class rate was $35 which is around $650 in todays value. But i dont have figures for second class.....I would guess its somewhere in between. Hope this helps!!
PS. If im not very accurate on these, may someone correct me.
