The 10 Centimes was struck in Copper or Bronze. It is listed in Krause under X# M8a (the first link you provide), and in Morin (Belgian catalogue) it is listed as M13 or Mor#13 (the second link), however the second link describes it as 5 Francs and this is incorrect because those were struck in silver.
But, the second link describes the known variants (number of sunbeams behind the column).
Quote: "Newtony"They are the same coin.

Both should be merged into one page...
Bronze or Copper medal - 37mm - Plain edge - 25g - Medal alignment. There is no counterpart as a real coin, but it circulated as 10 cent. The real 10 Cent was last minted in 1856 and was 32mm - 20g.
Silver medal - 37mm - Reeded edge - 25g .900 Ag - Coin alignment. This was the same as the 5 Franc coin.
Gold medal - 37mm - Reeded edge - 32,26g .900 Au - Coin alignment - Again there was no coin counterpart, but this was considered 100 Francs. Only a handful are known to exist.
@harryg - The 2F listed on eBay is a real coin and not a medal that circulated as a coin.
The 3 medals listed above were struck for the 50th Anniversary of Independence and do not bear any denomination.
