The mystery of Conan Doyle and the penny difference

Sir Arthur Conan Doyle's little book of essays about books and reading Through the Magic Door (1907) is a treasure trove of material that has inspired a whole string of articles. 

After taking a last look at these essays, I started working my way through Conan Doyle's autobiographical work Memories and Adventures (1924) in the hope of finding similar material.

I soon found something interesting from the days when he was a third-year student; it reminded me of an amusing, article-inspiring anecdote in the earlier work. 

From Memories and Adventures:

I used to be allowed twopence for my lunch, that being the price of a mutton pie, but near the pie shop was a second-hand book shop with a barrel full of old books and the legend “Your choice for 2d.” stuck above it. Often the price of my luncheon used to be spent on some sample out of this barrel, and I have within reach of my arm as I write these lines, copies of Gordon’s Tacitus, Temple’s works, Pope’s Homer, Addison’s Spectator and Swift’s works, which all came out of the twopenny box.”

In this previously-quoted extract from Through the Magic Door, Conan Doyle describes how he had to chose between spending his modest daily allowance on his lunch or on a book:

“...my student days, when times were not too affluent. Threepence was my modest allowance for my midday sandwich and glass of beer; but, as luck would have it, my way to the classes led past the most fascinating bookshop in the world. Outside the door of it stood a large tub filled with an ever-changing litter of tattered books, with a card above which announced that any volume therein could be purchased for the identical sum which I carried in my pocket.”

So what happened here?
Sir Arthur Conan Doyle believed that it was possible to communicate with the dead. If I could do that, I would ask him for an explanation!

As I have no way of contacting the great man, I will just have to guess why these two accounts differ in the detail.

Could Conan Doyle have misremembered details of his student days when creating the later work? Perhaps over the years threepence had changed in his mind to tuppence and the sandwich to a pie!

Perhaps he was remembering two different years and two different bookshops, with the threepenny version coming from his earlier years as a student. In connection with the later years, he mentioned that every shilling of his money was needed at home; perhaps he cut down and stopped buying beer.

Where is Sherlock Holmes when you need him!
