Circular coins that have a polygonal inner rim

Venezuela, 100 bolivares, 2001.

Venezuela copied the trick in its design series starting 1998.

One side had a polygonal inner rim, the other side standardly round.

The Colombian 500 pesos coin (only the "frog side") is a candidate too.

Do these belong here?

Two of them do.

they are very similar to the Swaziland coins up thread - I can't think of anywhere else (other than the aforementioned Swaziland coins) that started with a scalloped/ 7 sided coin - changed it to round but kept the original design exactly as it was.

Oddly with the Jamaican series the 1 Dollar got heavier - the 10 Dollars got lighter....

From scalloped to round? No, I can't think of any others right now.

Sorry, wasn't too clear with what I meant - that is,  started with a scalloped/ 7 sided coin - changed it to round but kept the original design exactly as it was.

Mexico did something that comes close. Until 2008 the lower denominations were round but had a polygonal or scalloped rim. In 2009 the 10, 20 and 50 centavos got a new (smaller) size, with a plain "same width" rim. The image (click the link if the coins are not displayed below) shows the old coins at the bottom, and the new ones at the top ...
