Largest Coin In Your Collection?

My largest coin is the Papua New Guinea Papua 10 Kina: http://en.numista.com/catalogue/pieces42217.html

At 45mm it won't fit in a 2.5x2.5 so I got a package of 2.5x2.5 mylar flips and put it in there. Works pretty good. I usually write the information on the 2x2 but I just printed out some papers with Microsoft Publisher that fit in the flip.

It IS possible to get cardboard - mylar 2 1/2 x 2 1/2s flips, AND 12 pocket 2 1/2 x 2 1/2 album pages.
Very convenient for the few large coins and medals that I have. The 12 pocket album pages fit quite conveniently in a standard 3 or 4 ring binder.

I ONLY use 4 ring binders. 20 crown size coins can weigh quite a bit, around half a kiogramme, in fact.
There is little less stress at the page holes, and therefore less of a problem with tearing at the holes.

the only pictures I have are groups of coins.

From my Birth Year Set:

Albania 25 Leke 60 MM




Haiti 25 Gourdes 60 MM

My largest coin is a 20 Balboa 1974 from Panama, one of these:

At 61 mms it is too big for 2,5 x 2,5s (which I otherwise use for large coins) so I have it in a little plastic bag, PVC free.
