After much digging inside in the area of where those were located. Many and I mean many were completely faded or just a maze of colors,,what could cause this? I am so disappointed. I know he valued his collection dearly someone mentioned box ghosts could this have been an acidic box they were in?
back in the days some albums had plastic softener in them, which caused stamps placed in them for long periods, or the right temperature/humidity, to OXIDIZE, changing some of the colors.
the EXCELLENT experiment by poster: John Becker shows one way of chemical change.
there are numerous ways for colors to change, and what Becker did is exactly what an experienced forger would do to achieve his result.
i'm not saying the person you
inherited this collection from is a forger, just that chemicals is the cause.
Danish Bicoloured stamps have been subject to these attempt at forging too for many years as some shades(prints) are quite valuable compared to others... especially the earliest ones.. later prints, depending on the chemicals used on the consistency in the color mixture used to make the stamp, could be altered to look like earlier prints.
and to the original poster: MrQuestion
many of the people on this forum are quite capable of making certificates themselves, they posses the knowledge and expertize.
and you don't acknowledge this at any point.
you ask question (fitting name) upon question, and people share their oppinions, but you never show appreciation or follow up with a simple thank you.
you just talk over, around or move to place a new question.
result is starting to show as people start to ignore.
perhaps you should think a little about this as it will greatly increase the assistance you'll get, here and where ever you go in your life.
