We stand behind everything we sell. We accept APS, PF, & PSE certificates on philatelic items. Encased holders are not accepted. Specific grades on certificates or confirmation of faults described in the listing. Or the inability of the agency to offer an opinion, will not be grounds for return. Tracking information should be available by the following evening. Please confirm that the item in the image matches the Title, Description & Specification fields. We list a lot of items. Very infrequently, a mix-up can occur. Likewise, if you do not receive what is imaged in the listing, you may return it. We strive to provide the highest quality images, of all sides, of every item we offer. We never enhance any image. What you see is what our scanners or cameras saw.
