those slabs look great, but (based on the coin in your photo) consider if the coins you are collecting are worth more, or less, than the holder they are in?
depending on the size of the collection you might want to consider SAFLIPS (SAF-T flips are not the same, they contain a small amount of vinyl).
I am in the midst of transferring my "one from each country" collection into them.
the extra pocket gives room to add a lot of detailed notes (mine will include a small map of where the country is) and leaves the coin readily accessible for photographing etc.
cost
and storage ratio is about 5:1 over slabs.
for my higher end collection (200 year old colonial stuff) I have considered slabs (currently in cardboard 2x2s). I LOVE the look of the PCCB ones but am nervous about safe long term storage. as far as I can tell with garage testing the shells are PETE (safe) and the inner holder is HDPE (safe) but until I can CONFIRM this there is no way I am putting coins worth $100 a piece into them.
PCCB has a thicker shell than world premier (by about double) and they seal together nice and tight. just need to confirm chemical composition.
the
Coin World premier is the next best. but they just stopped making white and black inserts. dark green is now the only color available (not my favorite when using with toned copper). if they still had black and white they would be my first choice.
the slabs you show look like lighthouse brand. I don't like the foam insert (too tight and it pillows around the edge of the coin) and the plastic shell is the thinnest I've seen of the 3.
hope this helps, and
