Circulation sets with a majority of non-circular coins

[<k>]

Circulations sets usually consist either of all round coins, or else they include one or more non-round coins: scalloped or polygonal coins. However, most sets contain a majority of round coins. A rare few do not. I wonder just how many there are? I will post some and see if the members can think of any more.

Swaziland: coins of the 1970s.

The Swaziland 1970s set contained just one round coin: the 1 lilangeni coin.

I do not even know whether it circulated.

Paraguay, 1953.

Paraguay issued four scalloped circulation coins in 1953,

Their denominations were 10, 15, 25 and 50 centimos.

These were part of a one year set.

Only one or two of the coins were round.

São Tomé and Príncipe / St Thomas and Prince.

The country issued a new design series in 1997. Of the 5 coins, only two were round.

Going off-topic for a moment, Swaziland 1 lilangeni coins do circulate -- in the UK, at least. I have several, all received in change in the UK in lieu of £1 coins.

Well spotted! Six non-circular coins out of nine.

I had heard of the phenomenon but have never been a victim of it. No wonder you had to move to Sweden.

We don't get the plagues of fakes in circulation here, either. 15 years or so ago there was an outbreak of 'ryska tior' (Russian tens), i.e. fake 10-kronor coins that originated in Ukraine (despite the name) but I have never seen one. I would quite like one to complement my extensive collection of fake £1s!
