plack

But, ere they came half gait to Concludendum, The fiend one plack was left for to defend him.

Plack, plak, n. a small copper coin formerly current in Scotland, equal in value to the third part of an English penny.

Will they not give us a letter of cursing for a plack, to last for a year, to curse all that look over our dyke?

I wad hae thought better o' it had thou made it when it took the last plack i' thy pouch.
