Rare coins can always wait til later, because when you have a lot more experience it becomes easier to notice under-priced rarities. Whereas there are no under-priced nice condition common coins, so for nice condition coins the beginner collector is playing in the same field as the more experienced collectors.
Good advice IMO.
Lucas- however, if you decide to specialize in a series, going for the rarest coin in the set, as soon as you see it, if its a good price, and you know what to look for, is often a great move. It may take years, and I mean years, before you see another example you like at a price you like.
Or the price can rise, sometimes dramatically.
About 2 years ago I saw the key to my campgate mint set for Constantine I, Ticinum mint. When I saw the price (about USD 48), I attempted not to pass out, (I have seen 2 other examples for sale in the last 5 years, at 150 and 200), bought it, and never have regretted it for a moment.
The dilemma when you are early in your collecting career is that you don't really know what
rarities are important.
Rare varieties which are the random
choice of
good or bad engravers on a Monday morning are completely unimportant. Spelling mistakes, omission or inclusion of dots, forgetting to leave out some symbol etc. There is almost no value placed on such "
mint errors" in ancient
numismatics.
Anecdote: Before I focussed on
Roman Republican coins I recall
buying a debased
Argenteus of Licinius for GBP145 which
had a spear rather than a
sceptre over the emperor's shoulder. The
type was not listed in
RIC. At the time, the
price was about twice what I would have paid for the
type which was listed in
RIC (some 25 years ago). It was not a
good buy, because I never went on to collect such coins comprehensively, and when I went to sell it the reaction was "there are
plenty of such random varieties in the late
Roman period, who cares?". Perhaps someone does care but as I hadn't gone comprehensive, I didn't have the knowledge to say whether the variety was important or not.
Rarities which are a result of changes in government monetary policy,
military upsets, political developments, changes in propaganda
themes, such as completely different
types, short-lived siege issues, a
rare mint for an otherwise common issue, or
rare magistrates or emperors on coins are tremendously important because they have a bearing on world
history.
So if you start by collecting
rarities, it is possible that you collect technically
rare but essentially unimportant coins. Thus if you do decide to go for "comprehensive" collecting (which implies you will need to get the
rare coins at some point) then I would encourage you to spend much more on books than coins at the early stage, and read read read relentlessly to discover what is important. Printed books which you have to buy
still contain a great deal more information than any web-sources.
In the end, every early collector will make mistakes (
mint errors!) in the early years. This is why the general advice to focus on
quality holds
good, because you can fix your mistakes by
selling the nice coins you bought. I didn't follow that path, but the general advice to focus first on
quality still holds
good.
