Norge 1 Ore

[pjm66]

Found a 1957 Norweigan 1 ore coin last night---man this thing is tiny. It is also a little grimy from all those years under the lilac bush in my back yard. The coin is bronze---what is the best way to clean it?

start with distilled water

Then what? Toothbrush?

Thanks for the reply...

for a beginner

you could use a toothpick or match stick to flick off dirt - slice the end off at an angle with a very sharp razor blade - no heavy pressure

for toothbrushes I prefer a chopped down brush from oral B

the best way - mechanical combined with long term soaking - is under a stereo microscope but that takes a long time to get used to



dish soap is generally not harmful to a coin like that and you can use warm water - you'd be surprised how effective that can be - helps get the surface dirt off

some use peroxide - I do not advocate that for copper - for a variety of reasons

no need to try electro - resale value is almost always destroyed - patience is key in cleaning EVERYTHING - some items soak for well over a year before the nasties break down and give up the glory and I would call that an average time needed - change water often, let the item dry every once in a while - don't scrub it too often or too long - the brush will tell you everything you need to know: brown = working


there are plenty of articles online related to coin cleaning - take them all with a grain of salt but there is alot of useful information to be found

How about some pictures and some after the cleaning?

Looks exactly like that except mine is from 1957. I managed to scrape a lot of the gunk of with a toothpick---will do more tonite. The coin is basically emerald green...patina, I assume?
