=== Frequency (coins) ===
* '''{{para|used_coins}}'''
* '''{{para|frequently_used_coins}}'''
* '''{{para|rarely_used_coins}}'''
* '''{{para|coin_article}}''' For example {{para|coin_article|<nowiki>[[United States coinage]]</nowiki>}}

* The {{para|coin_article}} parameter without an argument will result in {{code|<nowiki>[[Coins of the {{{currency_name|{{PAGENAMEBASE}}}}}|Coins]]</nowiki>}} in boldface type ''only if that article exists''. If that article does not exist, then "Coins" will be in bold and unlinked.
* Use symbol if possible. But it has to be correct down to the position and the spacing. If you are not sure, fall back to the full name. Central bank websites are a good source for authoritative information.
:'''Correct:'''
::$1, 10¢, £5, 500 Kč
:'''Incorrect:'''
::1$, $ 1, 10 ¢, ¢10, £ 5, 5£, 500Kč, Kč 500
*If the symbol is behind the numeral, then put the symbol after the last one.
:'''Recommended:'''
::20, 50, 100, 200, 500, 1000, 5000 Sk
:'''Not recommended:'''
::20 Sk, 50 Sk, 100 Sk, 200 Sk, 500 Sk, 1000 Sk, 5000 Sk
* Use the representation on the coin/banknote, e.g. if it says '''"100 cents"''', then it's "100 cents", not "1 dollar"; if it says '''"{{frac|1|2}} franc"''', then it's not "50 centimes"
* Use {{tlx|frac}}: <code><nowiki>{{frac|1|4}}</nowiki></code> &rarr; {{frac|1|4}}, not {{!xt|1/4}} nor {{!xt|¼}} 
* If the list involves both the subunits and the main unit, do not add a new line after the subunit. For example,
:'''Recommended:'''
::10p, 20p, 50p, £1
:'''Not recommended:'''
::10p, 20p, 50p<br/>£1
:However, add a new line with <nowiki><br/></nowiki> after the subunit '''if and only if''' the total number of lines remains the same.
:'''Recommended:'''
::10p, 20p, 50p<br/>
::£1, £2, £5
:'''Not recommended:'''
::10p, 20p, 50p, £1, £2,<br/>
::£5
* Do not put "and" before the last one, e.g. '''"1, 5, 10, 20, 50, 100 yuan"''', not "1, 5, 10, 20, 50, and 100 yuan"
* For large numbers, write like these
:* 1000 (no space, no comma)
:* 10&nbsp;000 (with &amp;nbsp;, not a regular space)
:* 100&nbsp;000 (with &amp;nbsp;, not a regular space)
:* 1&nbsp;000&nbsp;000 (with &amp;nbsp;, not a regular space)
:* 10<sup>7</sup> (or higher) (use {{tl|e}} if the number doesn't start with 1)

Frequent vs. rare comments:

* Smallest coins:
:* recently and officially phased out (e.g. 10 and 20 h of Czech koruna, 5 New Zealand cents)
:* not used in practice because of low value (1 and 5 South Korean won (maybe it's official now...))
* Denominations in the middle
:* Ask yourself this question: if you are given change when conducting a daily activity, and denomination X is required to make a mathematically minimal number of coins and banknotes. Would you receive denomination X? This applies to US 50¢ (historical reason about silver stuff in the 1960s) and 20 New Taiwan dollars (a new denomination lacks government support and campaign).
* Banknotes that are being replaced by coins (e.g. Brazilian real's R$1 coin gradually rendered the R$1 banknote obsolete).
* Large denominations
:* Ask yourself this question: do ATMs give this denomination? The answer is no for US$50 and US$100. This question also applies to denominations in the middle, e.g. ATMs in Iceland dispense 500, 1000, and 5000 króna notes, making 2000 króna notes "rarely used".
:* Ask yourself this question: When someone buys an electronic product that costs several times the largest denomination and pays in cash, are they likely to use denomination X?

You might be thinking, "why do these simple words "rare" and "frequent" have to turn into these long definitions?" The bottom line is, '''these definitions describe usage in daily life'''. The issuance numbers quoted by the central banks/governments have little relevance in this sense, as some denominations may be used for interbank transactions, foreign exchange, in casinos, for tax evasion, by criminal elements, etc.

'''And only use these attributes when you are very sure. If you are not, fall back to a single list where rarely and frequently are not distinguished.'''
