All the ddo for this year have a doubled mint-mark . So just take a image of the date and mint-mark . That's all we need .
If all mint marks for the 1995D are doubled, only DDO-003 has that wide of a spread on the date. That strong of a spread, sorry.
just because there may not be multiple varieties on a specific coin does not mean there are none to discover. while you may strike out a few times there is always a chance of a home run.
I find variety vista is the least helpful IMO. coppercoins.com shows 6 obv and 2 rev DD's. while doubleddie.com shows 7 obv and 5 rev DD's.
i am not certain that they are at that stage yet. some varieties only have doubling in certain locations. may be the date, motto, etc. if they use a reference site as a visual aid, and they use one with the least options, they might pass over something. for the sake of conversation if variety vista only had a listing of a coin that showed doubling in motto... the novice might only search that specific area associated with that year and MM. while another site may not show as many die stages and markers, they may have listings showing varieties that have doubling on only the date, or only LIBERTY. then that novice knows they can not limit themselves to just the motto as seen on the other site. it would be nice if they all communicated to each other the discoveries that are sent in and it would make it SO much easier to have all the knowledge in one location but i doubt they have that kind of time. i hope this gives a better understanding of my "opinion" as that is all it is.
I use them all and think wexler can be a slick willy on his coins with mint-marks . Why ? Most of the time on his ones with lots of DDO(s) he doesn't show the mint-mark placement on them all ..
I use Variety Vista the most because of what Rick pointed out. Most of the others just aren't in depth. Coneca has all the MM placements and an in depth visual of all the doubling on the coin, this is Key when trying to attribute a variety. and sometimes seeing that certain die crack, die polishing lines, or clash etc. is the only way to determine one variety from another.
Coneca operates the best out of all of them . They have different specialist for each denomination . Mr. Wiles does all the new discovery .
I agree in determining variety, however I was only speaking in terms as using those sites as a pictorial aid in comparing a coin that one might "think" is DD to what one actually is. telling someone about notching and split serifs and seeing it is different. they are what I used as learning tools as well as listening to the fine folk here.
Until 89' MM were hand punched into the individual dies, each one in a different location, and some slightly rotated. Looking at the MM placement is attribution 101. As far as the other sites, besides VV, they can all be useful, and each one has it's merits. I use them all. Have you ever tried to attribute a variety with CONECA's Master listings? it is a usefull tool they have in their site. this will give you the description of every variety they have seen, even though they do not have photos of the coin posted. http://varietyvista.com/CONECA Master Listings.htm
