Sometimes, polarized light may help to show up the date. Also may apply to Buffalo nickels with worn date areas. |

Nic-A-Date for nickels uses ferric chloride as the etchent, Silver can be etched with ferric nitrate. Haven't tried it though but that is what is listed on jewelry sites.

Looking around for ferric nitrate on the internet... that stuff isn't cheap!

I tried the rev/obv types but since the collar is worn you can't tell if OBV-02 or OBV-03. OBV-02 means that it would be a key date. Seems you're asking for hints for doing some destructive methods that may or may not reveal results. I to might do the same as a last resort. Plenty of suggestions have been presented or already available with a few searches through the forums. Curious if you've tried displaying images of the whole obverse and reverse that which others can evaluate? Some may or may not be able to put together or narrow down a nondestructive conclusion using design types or un-thought of markers? Thanks, Doug. Edited by Halo1st

It isn't that expensive. The Science Company sell 100 grams or crystal for $13. That's enough to make 1000 ml of a 10% solution. Now if you price the ready made solution that is considerably more. 125 ml of 10% solution is $24. So you can make 1000 ml for about $13, to buy that much ready made would cost over $200.
Carolina biological has 100 g for $9.70.
One word of warning though, using it on silver will form silver nitrate which can turn black on exposure to light. so any treated coins may turn black as well. You might be able to avoid that though by treating the coins in darkroom conditions and thoroughly rinsing the coins before exposure to light for examination.

@Conder101 if I need to it in darkroom conditions, will an ultraviolet black light turn the silver nitrate black?
Thanks

I have to admit I don't know. I don't know if it reacts to certain frequencies or if it is a matter of intensity.
