[Game] World Coins Time Machine… Counting Backward by Year! (Plus Prize Coin)

You can do 1464 with an Edward IV light coinage groat (48 grain) struck from heavy coinage dies. On 13th August 1464 the weight of a groat was reduced from 60 grains to 48. The heavy coinage dies had mm. Rose. As long as a die match can be made to a 60 grain coin confirming its use prior to 13th Aug. there is a full seven and a half months to the year end (OS). The light coinage rose marked issue lasted about a year, but there are equally common new dies to replace worn out ones. With the heavy dies continuing to be used into the light coinage these must be contiguous with the weight change which wasn't accompanied by a design change.

I don't have an example, but here is one. Link to the description is https://www.coinarchives.com/d8372df23a308bfc6db61b3b8a4d120d/img/dnw/160/image00779.jpg

@robp Thank you very much!! that is indeed some fantastic
research. What does the forum have to say?

 

@talerman here again some great sleuthing! I think this would be a
good candidate for 1463, what say the forum?

 

Looks good to me. Relevant section of the rules of the thread, posted by @Curtisimo who I guess has the final say:
"4. The coin should be datable to a specific year by some mark or characteristic. It doesn’t necessarily need to be minted with a written date as long as it can be confidently dated to a year. No date ranges (Ex.: a coin datable to 1630-1636 would not be usable). Feel free to share with us anything interesting about the dating of the coin in your post."

 

Agree with Paddy B. Could we count the Islamic coin for both 1462 and 1463 if necessary or is that pushing things too far ?

 

I agree with both the previous posts. I now see I have an AH 850 Indian coin, which could be 1446 or 1447, so I might be waiting in line again.

 

I would guess that this would be fine, the coin really does date to both years, and it is the calendar difference only.

Kind of like (well opposite) how 2019 is both Heisei (平成) era year 31 AND Reiwa (令和) era year 1 by regnal dating in Japan. The Gregorian year is split/combined based on a valid and recognized alternative calendar dating.

Has @Curtisimo been around lately? He should be the final arbiter of any questions.

edited to add: here is the copy/paste from the OP. Seems very much like it should be allowed.

5. Eastern and other coins that don’t use the Gregorian calendar are fair play even if the year doesn’t align perfectly as long as they are datable to ONE year in that calendar. At the bottom of the post just tell us the closest equivalent date in the Gregorian calendar. (Ex.: 1834/5)

 

A good idea but maybe pushing things a bit too far. I recommend deciding that an AH date equates to one AD date, without more evidence to support otherwise, and holding firm with that. But that could simply be my un-diagnosed OCD speaking. Storks most recent post would seem to support attributing an AH or other dating system to both. I'm game and amenable to a majority decision.

 

I messaged @Curtisimo regarding our dilemma. Maybe he can
offer some solutions.

 

Okay so I have given this a lot of thought. I think that it is fair game to allow the coins that are datable to one year in a non-Gregorian calendar to count for both years that it equates to in the Gregorian calendar as suggested above.

I would like to require that each year have a placeholder post with a coin that is “played” for that year only though. For example you can’t post a coin and say “this is good for 1412 and 1413.” You have to designate your post as one or the other. So if you chose to play that coin for 1412 you have to make another post for 1413, even if it is the same coin/coin-type.

That way there is clarity on the year and one could still read through the thread and identify at least one post for every year.

 

OP has spoken, I hear and obey!

 

With clarification from @Curtisimo , we can start our search and research . With what has been found so far, where exactly do we stand?

I am still busy with work....
But, I will check my Islamic material to see if I can help with AH dated coins.

1464 England Edward IV Groat nd but can be confirmed by historical evidence as being struck in 1463 posted by @robp

1463 Mamlouks of Egypt Dinar ashrafi AH 867 (=1462-3) posted by @talerman

Under @Curtisimo's rules I have to post formally this coin again to qualify for 1462, which I now do:

1462 Mamlouks of Egypt Dinar ashrafi AH 867 (=1462-3)

I now eagerly await someone, probably @tibor, producing a 1461

oopps

 

I'm having trouble posting a picture of coin I
found that would work.

Take your time I cannot pitch in till 1439!
