Coin "Collecting"

 I've never considered myself a numismatist -- I know next to nothing about coin values and would never buy the non-circulating coins recently sold in magazines or broadcast ads.     However, I live close enough to an International Travel Hub (tm) to have been given a number of interesting coins in my hat tips or pocket change, and the resulting rush of   "exotica"  prompted me to keep what I couldn't spend anyway   8)

I now possess a variety of Canadian coins (including one "Loony"  ($1) and a "Toony" ($2) -- my Canadian busker friends told me there isn't a paper denomination smaller than  $5 C).   I didn't know there were Canadian Centennial coins until I got a 1967 penny with a bird instead of a maple leaf.    My oldest  US wheat penny is 1939 -- Lincoln's head is nearly worn smooth.
There's an Indian-head nickel so smooth I can't find the date.      Last month a boy's father donated a 2003 gold Kennedy half-dollar, hermetically sealed in a hard plastic case  (seriously, there's no way to get it open   8).

Rounding out the Penny UN are:

A Bahamian 25-cent piece (with a sailboat on it)

Un Centisimo de la Republica de Panama (with a Mesoamerican Indian on it)

An English penny (depicting a portcullis and chains....?) and some fivepence (with thistles)

A Spanish Euro penny (a building with tall pointed towers)

An Irish penny (with a harp and a long-necked bird drawing with an even longer tail)

A tiny Euro penny with no country on it...only a Carnivale-type mask and two initials, an "R" and either a "J" or an "F")

A gold 10-cent piece from Hong Kong with a flower/large ornate leaf on it

A 10-cent piece from Singapore with a spray of leaves on it
