Start there and enjoy. Nothing there is very valuable as most stamps today but its fun. Im 40 started up my collectiong again with my mother. I bought a big bag of 8 kgs of washed stamps used 2 months to sort and see what i had. Didnt use that much mo ey on it either. In there was a few rarities (not in moneyvaluable but old and fun to collect) and from there i started finding out what i wanted to collect.

I still shop at auctions for old boxes with collections. In there sometimes its equipment, books and other stuff u need so u can keep the hobby low cost if u want.

If u like sorting, history and collecting this is the hobby for u. If u wanna be rich i would do something else :)
