How Many Are Known To Exist?

[dandelatorre-migration]

Hello,

I have a '1671 Estonia-Reval 2 Rundstuck'. Expert numismatists, reference books, World Coin catalogs, and representatives of several international auction houses all offer the same information... the coin is rare, there is no reference to value, and there are no records of any auction history.

I'm very new at coin collecting, and with very little knowledge. I can really use your help in helping me find out how many of these coins are actually known to exist, which

'Rarity Scale' is universally accepted, and are there differences in the 'grading criteria' for coins of this age and/or rarity?

 

I hope the images appeared!

Thank you for your attention,

Dan
