I sold over 2,000 boxes and mixtures of stamps in my life time ,absolutely none have been checked according to the discussion above .
Nobody ---yes ----nobody in the stamp trade checks their stamps for perforations and watermarks who deal in worldwide stamps . First, time doesn't allow it and second 99% of material coming across their desk isn't worth checking . Most dealers and I can view a glassine full of stamps or a huge ten box lot and pick out the better stamps on a quick one time view . Nobody is a expert on everything and we don't have to be ,we just know what is priemum and what is not, 98% of the time.
To say it is a uncheck lot --really ---you really think there is that many lots being sold today that hasn't gone thru 2 or 3 dealers hands in the past 20 years first . Most lots being sold today especially on
ebay have been purchased at one time thru major stamp auction firms and each lot has been reviewed by the firm and maybe by 6 or more bidders before it was sold to the happy
ebay seller .Who turns around and tells you it is unchecked ,yes it is unchecked by him ,but the experts and by that means 5 or 6 of them who are more experienced than your typical
ebay seller has already viewed the material.
