I have been a coin collector for a number of years.
My father collected for years, and I picked up the habit from him.
I prefer older coins, and I am always looking for holders/storage.
The holders are sturdy, strong, and extremely clear.
They are great for protecting coins.
The coins fit quite snug, but you need to be careful, they are hard to open after placing them.
I am using them for all size coins.
I just put a backing behind them to fit them perfectly.
Good quality and I highly recommend them.
Please see my pics for examples.
