I have removed the link to the website of the International Association of Professional Numismatists from the post below. My anti-virus program picked up some nasty malware on the whole page. This is probably linked to something a colleague sent me just a few minutes earlier, several people in US coin dealing and collecting circles have infected computers which at this very moment are sending out email messages containing malware to everyone in their address book. I'd recommend keeping away from collectors of ancient coins for a while (actually I'd recommend keeping away from most of them in general).
British archaeologist living and working in Warsaw, Poland. Since the early 1990s (or even longer) a primary interest has been research on artefact hunting and collecting and the market in portable antiquities in the international context and their effect on the archaeological record.
"coiney" - a term I use for private collector of dug up ancient coins, particularly a member of the Moneta-L forum or the ACCG
"heap-of-artefacts-on-a-table-collecting" the term rather speaks for itself, an accumulation of loose artefacts with no attempt to link each item with documented origins. Most often used to refer to metal detectorists (ice-cream tubs-full) and ancient coin collectors (Roman coins sold in aggregated bulk lots)
"tekkie" - metal detectorist/metal detecting (a form of artefact hunting)
