Hi BattleshipRB23
The kangaroo study will take a little time as the sheer volume of stamps must be individually recorded and plate positioned. The albums I have do not emit any odours or chemicals, some of my stamps are valued at thousands of dollars each (invoice not catalogue value) and keeping them away from everything damaging is top priority; in my case it has become a very expensive necessity.
I can easily purchase leather cases but I see no real importance it would have on my stamps when it comes to protection. With valuable stamps one would need to purchase a dry cabinet used for cameras and camera accessories with a built in digital thermometer, hygrometer, dehumidifier and a lockable door with rubber seal.
These cabinets may be expensive, especially when the largest is needed in my case but they are of great importance as they produce the ultimate protection against dust, sunlight, moisture and heat.
Also what increases protection for stamps is to isolate any with rust or foxing as damaging airborne pores from these stamps can travel to other stamps permanently damaging them.
I have seen an album that had a strong smell of mildew and the contents (all Australian stamps) were full of rusty stamps; that particular album was
inherited to a couple who wanted to sell the collection to me. I normally do not buy from the public but I knew these people and offered to buy the album if any interested me.
The collection consisted of about 250 stamps, and the market value would have been around the $8,000 - $9,000 mark, if not for the smell of mildew and major rusting on every stamp, the collection was worthless, one such stamp was a rare McCracken £1 Coronation specimen, I have the Ash £1 Coronation specimen (it is shown as my avatar), it was destroyed, there are less than 200 of the McCracken specimens in existence.
50 pages is quite a lot, my research kangaroos take up four A4 albums and one A3 album, a mammoth task; researching is time consuming but quite rewarding at the end.
