FYI - coin die varieties

Perhaps I could offer my developmental skills and knowledge to NGC, for a competitive fee\salary. I have participated in dozens of public facing websites and applications. This form would have been utterly rejected by the testing and roll out staff. The issues in this form should have been addressed during the initial unit testing phase. -

GRADED COINS NOT MATCHING PAST PERCENTAGES
dprince1138 replied to JGGLAD's topic in Newbie Coin Collecting Questions
Perhaps do a split next time and send half to one vendor and half to another and see what sort of comparative differences there are, if any. -
Of course, this would not be an easy task. With the expansive penny library and penny questions, I may go forward with designing a preliminary search engine, not including this functionality.

http://ec2-13-58-222-16.us-east-2.compute.amazonaws.com/wiki/Home While the following sites do not particularly provide the atomic level of information as in your example, I thought that it may be useful to provide links to other sources for coin information, particularly for die varieties. Dave's Bust Half Dollar http://maibockaddict.com/ Seated Liberty Half Dollars http://www.lsccweb.org/BillBugertBooks/Bugert-Vol-I-SF.pdf Seated Liberty Dimes https://www.seateddimevarieties.com/ Newman Numismatic Portal (all coins) https://nnp.wustl.edu/encyclopedia/catalog?catalogId=1 https://www.pcgs.com/coinfacts (all coins, to display a particular coin w/wo die variety, I enter the coin in google, then click on the appropriate PCGS link). Of course, https://www.ngccoin.com/variety-plus/united-states/ (all coins)

Does not look like it. Another consideration for a search engine could be a pixel\bit compare function. I have already created an application that automatically resizes all images in a folder to the same ratio.

Pretty penny. Excluding initial membership fee, grading a coin can run $45-$60, depending on options. For myself, I am about to submit coins for the first time, but I feel it is necessary to prove the value of the coin, which I am hoping to to sell for $250 or more. Although, some may do for collection purposes. Amazon sells very nice coin containers.

Of course, I should have indicated "financial transaction", rather than "money". I incorporate an enormous amount of data validation, data verification, database integrity, error tracking and recovery in my applications. I recall one of my professors lecturing about the necessity of accuracy and that 30% of code should be applied to that goal. If I do create a Die Variety search engine, you will see what I am referring to. The NGC online invoice application is an extremely poor example of proper programming. Not only the obvious data errors, but the design of the form as well. Example A is of bad data. Example B is of a bad record. There is a function path error as well. -

Speaking of developing a search engine interface. The NGC invoice application had a number of issues that should be unacceptable in a production environment, especially associated with money. -
