The formula I use for buying and selling kiloware.
Most mixes have around 4,500 stamps on paper per KG.
Off paper mixes are around 12,500 stamps per KG.
With kiloware numbers dropping dramatically as less and less people use the letter mailing system and also are not using stamps on their envelops.
Good unsorted kiloware is very difficult to find in this day and age.
Sadly it has been very common for people to try and soak the cancels off the stamps to sell them and this I believe has destroyed a huge amount of modern kiloware over the last 6 years in particular.
Biggest issue I come across with kiloware buyers is that they have had bad experiences in receiving lots of kiloware that had all the good stuff taken out only to leave stamps with very poor cancels. These comments come as I am thanked for the quality of our kiloware we sell mostly on eBay
. It really is a stand out. Sad really!
My charity contact is telling me that in coming numbers for their kiloware has fallen around 50% on last years numbers. But the year is still young and some donators could very easily have just not sent their stamps in to the charity as yet.
Working with kiloware as it grinds to an end. Have sorted kiloware most of my life. The one and only charity contact that I still have could supply me with around 300kg per month 10 years ago now 5kg per 3 months is all I get of the very recent stamps on paper these days and sometimes as little as 2kg per 3 months.
To me stamping is all about kiloware. All my stock comes from kiloware. Kiloware stops so do I.
