We have been a stamp collector and enthusiast for 50 years. We consider what we sell are fill ins for the advanced collector or stamps that may be preferred by any collector. We do not provide grading for stamps. We provide Scott numbers when we are sure and have tried to select stamps that are attractive to the eye and practical for mounting.
Stamps are excellent historic and educational tools.
