A close examination of each stamp is required, determining the watermark, perforations and checking for faults. Noone can determine the value of a collection without doing that.
That takes time, patience and a good stamp catalog. The grouping could be worth more than $1000. You will never get the right price for your stamps without taking the time to invest in them.
