Who sold the Voynich MS to Rudolf

[Anton]

After 1620 the Taler was deliberately deprecated, so it even makes sense for Mnisowsky not to talk about Talers.

Can't agree with that. Suppose 500 taler is worth N USD, and now we have neither talers nor ducats, but we don't say that the MS was bought by Rudolph for N USD, we say "600 ducats", because that was what he (supposedly) paid. Likewise, Mnisovsky would have said "500 taler", unless his report is corrupted by Marci. Like e.g. he said "500 taler which was worth 600 ducats back then", but then Marci truncated it for "600 ducats".
