I have never seen a 10¢ Admiral on a cheque - a parcel, perhaps.
I don't deny it could be from a parcel, but certainly 10¢ on a cheque would not be unheard of. Depends on the value of the cheque.
I have many that look like the ones that wert posted, but here are two, where the amount of tax was so high that they had to put the stamps on the back. No 10¢ Admirals available, I suppose.

The top cheque was written for the amount of $1,570 with .63¢ in Admirals on the reverse.
The second is written for the same amount, but only had .62¢.
These are cancelled with ink.
Both were written in 1923.
I'll also note that excise and war tax stamps were also used on cheques. I do have some of those with higher values, 6¢ 8¢,10¢ and 20¢.
