Smallest coin compared to biggest coin

Post a picture of your smallest coin compared to your biggest coin! This is my Herrenia Etruscilla sestertius compared to my Kysikos diobol. Sestertius size is 28 mm and diobol is 9mm

I don't remember where, but I posted these photos a while back in one of the forum posts of my 1797 ‘cartwheel’ tuppence next to an Indian gold fanam. 

The tuppence is 41mm, whereas the fanam is just 8mm.

And look at the difference in width!

Wow thats a huge difference! They look so good together

Thanks! It's funny how impractical they both would have been in circulation, but for the opposite reasons. 

The fanam would be so easy to lose as it is barely the size of a pinky fingernail, whereas the cartwheel twopences would be so cumbersome to carry, as they are a solid two ounces of copper (~57grams).

The Kysikos diobol is incredibly small next to that sestertius. I will look through my collection for my most extreme pieces too.

A ¼ real from Colombia, and if you will accept notgeld as coins, 5 million marks from Westfalia

The gobog is 77mm whereas the tiny Persian Tetartmorion is 5mm!

Yikes, that thing is huge!

Even the wheel besides the coin is bigger than it.

Speaking of greek tetartemorions, I got one last year (I've posted it on the Jan 2025 additions' thread). And before the pandemic I got one of that huge japanese 100 mon coins.

But I never thought of photographing them together.

Hi.

Not the biggest nor the smallest of my collection, but this coin and this medal were made for the same ruler! :

Minh Mang, from Annam

20mm for the coin, 120mm for the medal !

Not as spectacular as the previous ones, but still significant:

N#7393 at 42mm

N#21870 at 10.8mm

American Eagle vs. Miniature Gold Krugerrand

For weight, a 5 kopek from 1777 at 48,1 g and a nepalese dam at less than a tenth of a gram.

For diameter a 1 öre sm 1676 at 46,4 mm and a postumous imitation of a habbarid damma at ~6,9 mm.

Wow! Seeing some crazy comparisons, and leader right now is @Quant-Geek 

Are proto-coins/coins in weird shapes allowed? 
Because if so I have some even more extreme examples.

Yeah!

Alright then, the smaller coins remains unchanged but both of the larger ones are exchanged.

The new heaviest is a manilla ring (onoudu type, 1700-1800) at 106 grams.

The new largest in diameter is a kissi penny at about 370 mm, I can’t actually measure the exact length since my caliper only goes to 300.

Very interesting!

One image has both of them.

Largest - Panama 20 Balboa - 61mm in size, weight 129.59 grams with 119.72 grams of silver in it - N#26261

Melt on it when I got it was $147 NZ, went to $732 during $120 US an ounce, now $542 at US$83 an ounce.

Smallest Panama 2½ centavos - 10mm in size, weight 1.25 grams - pure muck metal known as a “Panama Pill” (Later copy of a tiny silver coin from the early 1900s) - N#9792

The Panama pill is my smallest coin, but not lightest. That is this one - N#46485

No photo sorry, but a single silver para of the Ottoman Empire (As in 1/4000th of a Turkish lira). The coin is 1mm larger at 11mm and 22% silver. However with these overheated silver prices, it still has 10 cents worth of silver in it!

1 Pfennig 1713 from the Electorate of Saxony 13.1 mm and 0.38 grams

5 Kopecks 1789 AM from the Russian Empire 42 mm and 50.06g
