Someone suggested trying to make similar boxes starting from a cardboard sheet. I will try.
Currently, I am storing my 4000 and more coins placed in 2x2 holders in various recycled boxes and Ikea plastic boxes.
In the beginning, I placed my coins in normal albums, but it was difficult to manage the growth of the collection (except that you leave a lot of empty slots), and then there was the problem of the different sizes of the coins of each country. Furthermore, the album are not aging very well (some now are more 40 year old)
I hope to have provided some help.
Thank you. I like that 650 coin holder. I could buy a nice 17th century thaler for what it would cost to buy enough of those for my collection.
I am seriously considering moving everything to double-row boxes, but it's not as nice to look through. One of the pleasures of a collection is to be able to see the collection. Or you are just hoarding.
Yes! I agree, that is one of the troubles with using the binder pages. Make sure to leave empty spaces to be able to add coins without having to move everything up a spot.
Casual collector, world coins by type.
