Empty Coin Tray to fill

So here’s my problem , I bought a coin tray for the Marshall Island Aeroplane coins with 24 slots, however slots are only suitable for crowns ( without capsules) which I don’t want to do., or coins in capsules 35 mm, which the aeroplanes were.

Then I obtained a bespoke album for the aeroplane coins , so now I have a lovely box for 24 coins but no coins of the appropriate diameter .

so I thought Numista users would have some great ideas of what nice coins to collect (nit too dear) that would fit number 24 and size 3435 mm.

HERE are some coins in the range of 34 mm +/- 0.5 mm

Or a more affordable option if you don't mind a few MM here and there. You can stack and be a prepper at the same time!

Why not put some of your Fav coins in these trays? After all if the coins are expose to sunlight they would be damage after long term exposure. So I would advise to display some thing nice instead or something after toning will looking nice.

Knew people would have some ideas

Why not put dime sized silver coins in it? I mean you can get common date barber dimes in G4 for about $3 a dime. Mercury & roosevelt common date dimes you could get in G4-VF for probably a dollar or two. I would imagine this applies pretty closely for common foreign coins this size. But it is always satisfying to own a tray of silver.
