Firstly you have people scared of their money depriciating and people are hoarding onto whatever seems valuable just like precious metal bullions.
Secondly, people are getting more informed about coins than previously before as you have the internet etc, hence previous thought to be "not-too-valuable" coins suddenly increase in prices.
Thirdly, on really rare or scarce coins, counterfeit coins are popping out from nowhere and starting to flood the market, and hence making a genuine find ridiciously difficult.
In my particular field of Russian coins, jesus, within 3 years, coin values have blown more than three times the value, which makes it almost unbelievable. I used to be able to find ridiciously sweet deals once every two-three months, but right now particularly this year, finding one seems to be looking for an ant in a haystick
I honestly don't know what to do now... it is not like I can spend three times more money on coins... and I think it's time for me to move into another particular field
Does anyone happen to know some decent dealers that sell coins in bulk, particularly 19th century ones? It just happens that modern mintage coins don't really interest me...
Perhaps, I will get ideas on what I will want to collect next... thanks to the really expensive coin field that I am stuck with
