Oversize coins management

I guess I will not be the only one trying to figure this one out...

There are a couple of commemoratives that slightly get off the normal coin sizes (above crown), lets say 40mm, 2x2's that I use goes up to 39.5mm

So there are few options for me, keep this coins in a plastic sleeve that can hold the coin and at the same time fit the coin album pages, the only thing is that they will not look equal (First world problem)

Why the mints does not consider the problems they make to us before releasing commemoratives Anyone in the same boat? satisfied with the plastic sleeves solution or had another brilliant idea how to solve these kind of problems???

I usually put those oversized coins in a 2.5x2.5 flip from 42.5mm diameter and cut carefull the edges , untill it is 2x2, make sure you cut the same from every side, otherwise the coin is not in the center, what gives a dumb effect.

I'm pretty sure there are also some German states coins, or modern bullion with diameters way above 40mm...

I have several of these oversized coins, the largest being this 61mm monster -

I actually bought it during happier times with the intention of using it as a coaster but just couldn't bring myself to do it. Although this particular coin lives at the bank I have several of those larger silver proofs issued by several Island Nations during the 70s which can't be shoehorned into a 2x2 album slot. I keep these in the pouch on the inside front and back covers of the binders.

There was a company that made 2.5 x 2.5 holders with an opening large enough to accommodate a Bahamas 5 dollar coin (45mm). The company claimed the size was not profitable, and they quit making them.

I hunt these, and have had some luck in finding them in dealers' stocks of older supplies.

Of course, even these would not help you with the Panama 20 balboas, or similar "hockey pucks".

​Here, in Holland, we have them in 40/43/48/53 mm diameter and then the outside is 67x67 mm.
If you like I buy some and send them to you.

I don't remember from where I got it from but I have one (actually a few of various sizes larger than standard mylar/plastic flips) that accommodates my 1953 Coronation medallion of 48mm comfortably. The rest I've used for storing my military medals in instead of coins. So there's definitely someone out there providing flips larger than crownsize coins.

Hartberger makes a 2.5x2.5 flip, with album pages to match. I usually order them from http://prinzuk.co.uk.

I was not talking about flips; I was talking about cardboard holders that you staple to close.

​Sorry. I used the wrong term. Hartberger makes a 2.5x2.5 cardboard holder, with album pages to match. I usually order them from http://prinzuk.co.uk.

I've only used the self-adhesive holders and not the ones that you have to staple, but perhaps they also supply the non-adhesive ones.

Thank you for your replies...

This is one of the problems I face

this one is an odd shape and 48mm https://en.numista.com/catalogue/pieces85071.html

​My only solution for Tonga rectangles is to staple them into a flip.

Saflips makes a 2.5 x 2.5 inch size which will accommodate coins up to 48 or even 50mm in size.

My Cristina 1 copper ore of 1648 comfortably lives in one, same with Bahamas 10 dollar coins, Tonga 2 Pa'angas and those 42 - 45mm monster coins put out in 1970s Franklin Mint sets.

 

Fortunately my Panama 20 Balboa (Everyone's favourite comically large late 20th century coin) still sits inside its original cardboard packaging and is holding up well! But yeah - there's no way anyone makes a holder or flip for anything that large and usually the gimmick for 1kg, 10kg, 5kg etc bullion coins and rounds comes with a free case and capsule. Seriously you drop a 1kg silver coin on someone's foot and they will be limping.

Yeah, you need 67x67mm cardboards and almost everything fits inside, including all of the Oceania. You will not fit in extremes and the Thai bullet or Swedish plate money but you can handle that I believe. 50mm one isn't enough even for thalers. Any instead of 20 cardboards for A4 format, you get neat 12. I tend to put these at the end of the country in albums.

PS why stapled ones and not self adhesive? Air still gets in and it gets unevenly oxidated? Especially in albums where although sheets are ok, fresh covers are not so you get everything, learned it harder way…
