Colombia leper colony [gelöst]

Hi,

I'm curious about a mark on a coin. These leper colony coins of Colombia bear three marks: "B", "H" and "RH" according to Krause. I can't figure out what they stand for. It seems reasonable that they stand for a mint. The designs look to similar for a distinct designer.
I can imagine "B" stands for Bogota and "H" for Heaton (?). But for what stands "RH"?
Anyone with some understanding of these coins or with a good imagination?

Thanks in advance

Looking at my mint marks section of the book there isn't a RH recorded under Colombia. Heaton Mint was used in 1912...the only thing I can think of is Birmingham (RH) which was the Heaton mint anyway.

 It is a very long page, but halfway down (below a piece about other colonies) is the Colombia details.
Quote: The initials, “RH”, believed to be that of the designer, are located under the ribbon. A number of varieties are known for the 50 centavo pieces, where some of the letters were re-cut. A two centavo piece from 1921 uses the same Maltese Cross, but the initials “RH” are missing.

 Of the 12 coins on there I see some have no letters after the year, some have B which I see the coin has the word Bogota on the reverse, for H letter against the year I see a wide H letter below the ribbon. All those that have RH against the year do have the wreath design on the reverse, and now I read the above article I can see RH below wreath. So now to find out who RH was ...

Thanks for your input, I really apreciate it.
It still seems a bit off to me that coins with such small differences would have different designers... Or that only on one kind of coin the designer initials are mentioned. But, then again, it would be as good as an explanation as my mint mark theory.

Maybe there is someone with a Colombian coin catalogue at hand?
