Without an accurate weight we won't be able to help.
Try ad get your local postal outlet to weigh it.
"Dipping" is not considered cleaning...

If it was a dime planchet, it would be nickel coloured, magnetic and weigh 2.07 grams.
Also it would not be fully formed as a dime planchet is smaller.
Really need the weight to two decimal points.

Possibly plated after minting, but without a weight it's hard to know.

Looks kind of good, it seems a little off center but as mentioned a weight would be most important

It could be result of exposure to some chemicals.
Some years ago I did a study on how coin cleaning affects the surface and the color of copper coins.
The coin in the photo looks the same color as after being dipped into a common polisher named "Brasso" which is ammonia based
Short exposure to ammonia (no rubbing!) gives copper (bronze, to be accurate) cents the color of an old brass.

Here it just took me minutes to do this, regular 1978 1 cent and one with a Brasso soaked / cleaned 1978 [ 2 minute soak]. Note the difference in colors.

We will need the weight and pictures out of the 2x2 flip so we can see better details on the coin. I think I see weak letters on both reverse and obverse which could point to an under sized planchet.

It could be on a dime planchet or a foreign planchet since RCM minted for many countries.

If you check the French Site under the 1978 1 cents, they have one there that looks identical.

Could be struck on a Bangladesh 25 Poisha planchet, which weighs 2.7 g and has a 19 mm diameter.

thynium - Here's one I just got back from getting certified and its in the same league as yours. Maybe give CCCS a call, hes the only one in Canada to Certify this for you. Note how we identified the planchet. Would be nice to zap that coin first before sending it in and identify the country of origan for that planchet. Do your CSI work to perfection [Coin Seen Investigation] It will be well spent time and money on your part. You got some thing special there!!
