Archaeo-blogger Paul Barford has highlighted a CNBC article about investors and rare coins. Though there may be some unstated implication a recent run-up in coin prices caused by American investors will encourage looting of archaeological sites in source countries, CPO doubts it. First, CPO suspects most investors are focusing on high quality American coins and modern foreign issues. Ancient coins by comparison are far less accessible, far harder to grade, and have so many subjective factors associated with their value that by comparison they don't make for an "easy" way to "make a fast buck."
CPO does acknowledge that there has been a long-term increase in the value of high-quality ancient coins, but this trend probably relates more to a relative decline in the value of the dollar and a large increase in the numbers of wealthy collectors in "source countries" than anything else. So Mr. Barford and his friends in the archaeological blogosphere should have little to worry about if American investors take a shine to historical coins.
