Very interesting post..
I don't have currencies from any of these countries.. but I have from Sri Lanka, Malaysia, Thailand, US, Euro Singapore Denmark Qatar UAE and a few more.
I used to have coin collection during school days and I had some rare old Indian coins too but my dad took them away one day to use in his office to settle account. He was working in a bank. I had to rebuild the collection later.
I still have stamp collection from my school days. We also used to collect match box labels during our school time. But it was glued to some notebooks..or just kept as bundles in rubber bands. I don't know if any of my friends still have it.
Not sure if kids these days collect items like these.. we used to have lot of cards to collect.
Thanks for the post.. brought back lot of memories
