For information purpose only . . very expensive fish ?
If the photo is taken after 1946 (and it's assumed given the colour photo), it's undoubtless 2000 HUF (Hungarian forints), reintroduced in Aug 1946. At that time 1Ft approx. = 0.08 USD of 1946, and this conversion factor remained fairly stable for a little over 20 years, then the forint began to depreciate dramatically.
With this conversion factor, a trout would have been priced in the '50s at 2000 * 0.08 / 3 or 4 (3 or 4 medium-sized trout in 1 kg ?) = 40 / 50 USD at the time . . of course impossible !
I think the photo is much more recent, and if it's from the last months, as today 1 Ft = approx. 0.003 USD one trout would then be priced at abt 2000 / 300 / 3 or 4 i.e. 1,7 / 2.2 current USD . .
I find it then very cheap, in Belgium a quality fresh trout of medium size (250 g), locally farmed, is currently priced approx. 3.5 EUR i.e. +/- 4 USD.
Am I wrong somewhere ?
Kind regards to All,
near to Antwerp, Belgium
