Are These Mixed Lot Worth Anything?

All of your GB stamps with the exception of the two George vi ones are worthless. The George vi ten pence is the pick of the bunch of GB stamps with a nice CDS and looks undamaged. Not worth a great deal but it looks a nice stamp.

If a stamp is torn or even a perf is missing the stamp is damaged and almost worthless. The only exception is if it is extremely old or rare. Even then the value is depreciated. That is why when taking them off envelopes it is extremely important not to damage the stamp in any way. Many of the older stamps didn't have perforations and the stamps were separated by cutting them with scissors. Those are imperforate stamps and they have their own rules. Many of those stamps were cut off center or even the image was cut into on one side. They again are priced according to Grade and condition.
