Extremely battered metal detecting find, what was it? [solved]

Had it a couple of years and every time I have tried to identify it, I've come up with nothing and just thrown it into the junk pile.

It's approx 23.7mm. I'm sorry I don't have an accurate weight atm.

It appears to have the date 1818, it also looks like it says crown, and maybe even Britain?

The camera makes it look a lot paler than it actually is. It is actually a more gold colour.

I think I can make out the words "OF GREAT BRITAIN" on your coin....

Either way, even though it's honestly far too corroded to make much out I think it's a token rather than a coin; no British coin bore the name "Great Britain" in English.

I cropped images and put them on here ...



................. Obverse ................. / ................. Reverse ...................

I have seen similar, and they are usually a UK token for a royalty souvenir.
I have some (links below), and on yours is CROWN'D so sounds like one of those tokens.
Other lettering: 1818 ACCES(SION) 183? CROWN(E)D SEP 8 1831 ....
so that would make it a William IV token.
I put in some lettering (green definite, yellow maybe), plus reverse has what looks
like a wreath or plant in middle left.

Some of the missing reverse lettering on the left may be MAR(RIE)D JUL 11 1818 from ...

and the other may be an abbreviation of ACCESSION JUNE 26 1830 from ...
https://en.wikipedia.org/wiki/William_IV_of_the_United_Kingdom

So reverse may be: MAR'D JUL 11 1818 * ACCES JUNE 26 1830 * CROWN'D SEP 8 1831
Obverse may be: WILLIAM IV KING OF GREAT BRITAIN

Mine are not like yours, but they show the type of token it is similar to ...

where just over halfway down that page, number 53 (after 52 but with a dot) lists ...

Obverse. Bust to right.
WILLIAM IV KING OF GREAT BRITAIN
below bust,
BORN AUG . 21 . 1765

Reverse. A willow branch; above in three lines,
THE REFORM BILL PASSED 1832
a dash; in three lines,
ABOLITION OF SLAVERY 1834
below,
DIED JUNE 20 1837
around,
MAR D JULY 11 1818 . ACCES . JUNE 26 1830 . CROWN D SEP 8 1831

Thank you both. I did suspect it might be a token/medallion.

Great work ZacUK. You have a much better eye for this than me, I couldn't spot half of these things on the coin. I'm also curious how you did the the overlay on the coins?

PhotoScape - it does rotating, cropping, overlaying, and much more.

It is a free download, which I learned about from that topic; those images on
that link are to show the Crop part. For Overlay go to the Object part - like this ...

where below left of the main image are 6 icons, and select the T letter, which brings up a box
which contains what is to be overlayed, whether it be a single letter or number, or a series
of words. Already added 18 at top and just adding another 1 for the date (shown in the middle)
and the box it appears in can be enlarged and rotated, or typeface changed, or the colour.
It is a very good program.
In earlier reply I added in green for what I could see, then when I found that listing page worked
out what some of the other unknowns were, in yellow. On the obverse I have so far just put
both of those, but there are still gaps - and not sure what the wording is below the line.
Similarly on the reverse - cannot see anything in the middle part - not a single letter.
Thanks!

​Definitely agreed, that was straight up awesome detective work!
