Sometimes the toning is hard to capture on a coin, the slab doesn't make it any easier. You may need three lamps and may need to filter one or two of them. In any case that is a sweet looking toner.
Looks counterfeit. Take a close look at the R and I in Pluribis. that complete part looks like an extra addition coming forth from the cap. It shouldn't look like that, the font also looks off.
I tried so many different methods but have finally settled for the two I find the easiest. Better coins in Airtites and in Airtite tubes. Lower grade coin in Saflips and in a box.
I collect mainly for numismatic value. But with the recent drop in gold, its got me thinking about buying world gold coins. Most stores and online dealers treat them like bullion coins. If I can find some places that don't charge a large premium I would pick some up.
I really like Silver Certificate Large Notes, would like to get more too if they weren't so expensive. But I also collect many other series including small sized notes.
Some really good looking notes. Its always important to look on the back of the note. I'm guessing most people fold their notes towards the reverse, thus the marks are usually more distinguished on that side.
The Hawaii notes are a bit different then the North Africa notes. In a way they are harder because of the print runs. I am not entirely sure on exact specifics but the one dollar Hawaii notes that has A prefixes carry a large premium, especially in high grades. Also note that the Hawaii $20 and North Africa $10 notes has another series that does not have the A after the year. These are usually more expensive as well.
Wish I had seen your thread before you decided to use an eraser. Basically any rubbing of foreign material would take some layer of paper off. If you do decide to send it in to grade it just may come back with a NET grade.
In the future if you must remove light pencil marks from any printed media you should be using a kneaded eraser. These erasers are like soft clay and can basically pick up pencil marks rather than rub them off. And when using them you should still go easy and just roll them back and forth over the surface rather than rubbing on the paper.
Are the sleeves you want the top loading ones? If thats the case the holders from SuperSafe or basically any brand that mentions top loading are the ones you want. There are two major things you should look out for. The thickness of the material and the fact that it is PVC / vinyl free.
