Collecting by Type

When people collect by Type do you collect by KM # or do you collect
KM 122.1, 122.2 and 122.3 as on example

https://en.numista.com/catalogue/pieces2151.html

I am just not sure If I should keep both 2.1 and 2.3 or just one of this 20 haleru because the are both KM # 2

Any suggestions would be great

for the 20 haler coins, I kept both, because they are distinctive, you can easily say this one is KM2.1 and this one KM2.3, because the number 2 has another shape

obviously, that things happens with the edges, but also there are different KM numbers (or new coins) which possibly have the diameter and thickness almost the same like older ones, e.g. Tongan 2011 coíns and older

I try to collect 122.1, 122.2 ...
But sometimes it´s difficult to know which coin you have.
But there is a great side which shows a lot of pictures. 1 picture says really more than 1000 words...

I do collect both KM# or Y# or what ever in the versions 1.1, 1.2 etc. afterall the coins are always different.
Besides this I do also collect by mint mark, coins with the same KM# and different mintmaks as in the German and Dutch coins amoung other countries.

I collect by type
and i dont collect by subKMs

i have few coins, which i collect by type, but have subKMs
for ex:
https://en.numista.com/catalogue/pieces52214.html
now i have 1 and 2 types but want to have all 3 types of this coin

there are 3-4 coins, which i have (or want to have) all subKMs, subtypes

I collect all  circulation coins ( or coins which were  struck for circulation)  by  KM, Y, etc, and subtypes too. Also I try to find  enw subtypes, which  I know  will be added soon to  KM#.

regarding  commemoratives...  I  try to  get  at least one type.

For example, if I have " world Fisheries Conference"  in Copper-Nickel, Its enough for me. But if I will catch also  silver one, - sure, it willnot  go to the swaplist  But I dont  declare special hunting  for  silver one

Thanks. Good advise

Sometimes I have underKM, but Idon´t see the differences. I know where and what it is, but my eyes don´t see it.
But for example this coin:
https://en.numista.com/catalogue/pieces2063.html
is really different. I think I blind man could see it without using hands ;-)

thes subtypes are  very visible. you dont need any  glasses or something else to  see  the difference in eagle sizes. I was  little boy  and didnot know  what is  Krause catalog, but these    Zlot subtyes I had in my collection as different types of same denomination .

I collect normal circulation coins by type only. I arrange them per era and I couldn't care less about sub KM numbers.For example I don't care if a coin's metal changed from cupro-nickel to nickel plated steel, as the two are quite hard to distinguish in the first place.

I also ignore for instance the Dutch-French legends for Belgian coins and only have one language per monetary type. Same for South African coins with ever so many linguistic variants.

But there is one coin where the numista catalogue seriously bothers me:

https://en.numista.com/catalogue/pieces2064.mobile.html

This Polish 2 Zlote Y#80.1 & 80.2 are the cause that according to my dashboard I have 4621 coins and 4620 types. I classify the 80.1 one as the 1957-1980 era and 80.2 as the 1984-1987 era. This is why I have both.

Can someone finally change the catalogue for this?

So, silver  quarter and nickel quarter for  you is same?  just a quarter with same design... its  looks  odd for me.   

so would you keep both KM's of this coin ?
https://en.numista.com/catalogue/pieces432.html

If there are subtypes for a KM I collect them too.  So in your example of the Canadian 1 Cent, I do have both.  I figure if the design change is significant enough for a sub KM# I'll take it.

There are also other annotations in the catalog that I will keep.  For example: https://en.numista.com/catalogue/pieces388.html.  It has a small date year, then a design change for the date, and then there is a maple leaf on some of the 1947's.

Collecting coins in it's all diversity is as question of choice. I do really like to see the anomalies/differencies in coins that should be the same.
I'd say take a close look to the dutch Juliana 1 cents or the French 5, 10 en 20 centimes. Very addictive to collect all those diffent coins with the same KM.
Anyway what fits me doesn't need to fit others too, so make your choice!

I collect by type of the coin.
If I somehow or accidently got a coin with some small detail (mintage letter, dot, symbol, etc.) I keep it, but I do not specially look for that type of coin.

Dato, a switch from precious metal to non-precious metal I find significant enough to collect both, so I have a dime, quarter and half both compositions. It also sigifies a change in monetary conditions.

I think same is with copper VS copper clad steel
Brass VS Brass pl. steel
Brass VS al/ Bz
etc..

anyway, collecting  coins is a pleasure so  each of us decides for himself what to collect..

  I started  also  with only types, then  began  collect subtypes. and now I sorry about coins which I once swapped out, just because  they were   proof ,  or essai ( the reason: why I need one proof  coin from set if I have already whole set non-proof... same  with essais )...  Now I think - why???  What could happend if they were also in collection  

haha    but still sorry about  my stupid  steps in early years
