Hi Michal,
Where the estimate is included as
part of the original description for the coin then that information remains. You do not need to pay to see it. However estimates can be a very unreliable indicators of value because there is no
consistency between
auction house in how they are set. There is at least one
auction house for example which sets its estimates well below the prices its coins realise. I ignore its estimates.
What you have to pay to see are the actual values realised at
auction, excluding
auction fees which vary from one
auction firm to another. If you intend to buy lots of coins then it is a small
price to pay to get information which can aid you you establish what you might be prepared to pay for something. if not, then it might not be feasible for you. Only you can judge that.
I recommend you take the time to read the
FORVM rules. Discussion of value of coins is generally prohibited. The rules are strictly observed here and designed to aid the discussion as well as people new to the hobby but easy for newcomers to fall afoul of them if they do not read them first.
I do not have a gauge for the relative
rarity of your particular coin. However there are only a handful of examples of similar coins which I could find on
acsearch. Having said this,
auction records can be deceptive in this respect. The
auction records are biased toward higher end coins which
auction houses sell and therefore coins which are common can in fact appear
scarce if consulting
auction records alone.
