Thanks. Ironically, it is cheaper to get coins such as these outside India, even including the shipping cost.  ::)

On a related note, I wonder if the metal composition of certain coins makes them more condusive to developing "rainbow" patinas naturally. I have been told that sulphur in the air creates such patinas. But I have had a particular Vitellius Denarius develop a beutiful one in less than a year while others in the same environment have not.

Has the coin been chemically cleaned in recent times? this can lead to peculiar toning colours

I do not believe so, but I acquired it as it stands. Such treatment produces uniform patinas (many US-based dealers come to mind, who "specialize" in creating such patinas artificially) rather than "patches" such as thse. It came from a reputed dealer/collector I trust.

The spots at 9 and 10 o'clock indeed look sulphur induced, but is not necessarily air pollution. It may have been in bad quality paper or from a finger.

An unidentified coin is a piece of metal. An identified coin is a piece of history.

Thanks. This would explain why they are in specific locations only.
On high-grade Seleukid coins and certain republican denarii, I have often seen rainbow colours around the edges of raised areas.

If it's along the edge on both sides it was likely bad paper enveloppes. If it's on one side, it's more likely to be a bad quality coin cabinet or its lining. The bottom line is that in all cases, it's just chemical detritus.
