Often the high end of the spectrum is overseas Ebay sales from the UK or Europe - RICS are relatively rarer there then they are in North America and hence tend to sell for more.
Also as it is a leftie - there are fewer LH folks looking for a RIC bass. So fewer people wanting one.
On the positive side - it is a very early example of a reissue of Maccas own bass... So your odds of shifting it are certainly higher then if it were a lefty 3001 or 2030 instead!
